. A storm sewer is carrying snow melt containing 1.200 g/L of sodium chloride into a small stream. The stream has a naturally occurring sodium chloride concentration of 20 mg/L. If the storm sewer flow rate is 2,000 L/min and the stream flow rate is 2.0 m3 /s, what is the concentration of salt in the stream after the discharge point? Assume that the sewer flow and the stream flow are completely mixed, that the salt is a conservative substance (it does not react), and that the system is at steady state.
Answers
Answer:
Explanation:
In the steady state total volume going out will be equal to total volume coming in , and
total salt coming in = total salt going out
Total volume coming in per minute = 2000 + 2 x 10³ x 60
= 122000 L .
Total salt coming in per minute = 1200 x 2000 + 20 x 2 x 10³ x 60
= 2400000 + 2400000 mg
= 4800000 mg
volume of water going out per minute = 122000 L
Total salt going out per minute = 4800000 mg
concentration of water going out = 4800000 / 122000
= 39.344 mg / L

Rosie Milojevic, Business Development at iComplied
Answered 3 years ago
For those who run or work in a business that handles food, you understand the importance of food safety and regulation compliance as it pertains to not only to certification and licensing of a company, but also the life or death of those who consume the products. Because food safety is such an important issue, we want to ensure that all companies who work in the production, preparation, or processing of food have the tools and information they need to ensure they are in full compliance 100% of the time. One slip in food safety compliance could cost someone their health or life, and this information spreads mistrust in the general public toward the company who sold the product, and also the entire product across companies throughout an entire country and beyond. So how does each company working with food ensure they comply with each and every food safety regulation? Through excellent auditing tools.
Auditing in Food Safety Must Change
Auditing in food safety compliance is essential in ensuring that all regulations are being complied with. Most auditing practices for major companies are severely out of date. Many rely on several different forms, stacks of paperwork, and data stored on multiple different computers and databases. This is incredibly inefficient, as it can be easy to miss something when comparing one sheet to the next, and paper can easily be lost or destroyed. It is also time consuming for companies to share audits over separate computers and databases, as it must be passed down from one employee to the next. Technology has granted all food safety compliance managers a simple solution. Auditing apps are the new wave solutions for companies who want all of their data stored on one cloud database that is instantly accessible with real-time data for all employees. This means that no one ever gets left out of the loop, and no new information will fall through the cracks.
based on elasticity theory, the stress is predicted to be infinite at a re-entrant corner of a plane stress model. to avoid false answers using the finite element method based on linear elastic material model assumptions, what must be done to the model?
Answers
"Use a theory that accounts for material yielding" to avoid false answers that use the method of finite elements based on linear elastic material model assumptions.
What is termed as the elasticity theory for stress?The ability of solid materials to deform when subjected to an external force and then return to their initial shape after forces have been removed is referred to as elasticity. The external force acting on a specific area is referred to as stress, and the degree of deformation is referred to as strain.Linear elasticity's fundamental "linearizing" assumptions are: infinitesimal strains or "limited" deformations (or strains), and linear relationships between stress and strain components. Furthermore, linear elasticity is only valid for stress states that don't result in yielding.Thus, "Use a theory that accounts for material yielding" to avoid false answers that use the method of finite elements based on linear elastic material model assumptions.

You find an unnamed fluid in the lab we will call Fluid A. Fluid A has a specific gravity of 1.65 and a dynamic viscosity of 210 centipoise [cP]. What is the kinematic viscosity of Fluid A, in units of stokes [St]
Answers
Answer:
1.2727 stokes
Explanation:
specific gravity of fluid A = 1.65
Dynamic viscosity = 210 centipoise
Calculate the kinematic viscosity of Fluid A
First step : determine the density of fluid A
Pa = Pw * Specific gravity = 1000 * 1.65 = 1650 kg/m^3
next : convert dynamic viscosity to kg/m-s
210 centipoise = 0.21 kg/m-s
Kinetic viscosity of Fluid A = dynamic viscosity / density of fluid A
= 0.21 / 1650 = 1.2727 * 10^-4 m^2/sec
Convert to stokes = 1.2727 stokes
2. The moist weight of 0.1 ft3 of soil is 12.2 lb. If the moisture content is 12% and the specific gravity of soil solids is 2.72, determine the following: a) dry unit weight, b) void ratio, c) porosity, d) degree of saturation, and e) volume occupied by water.
Answers
The answers to dry unit weight, void ratio, porosity, degree of saturation, volume occupied by water are respectively;
γ_d = 108.93 lb/ft³; e = 0.56; n = 0.36; S = 0.58; V_w = 0.021 ft³
Calculation of Volume and Weight of soil
We are given;
Moist weight; W = 12.2 lb
Volume of moist soil; V = 0.1 ft³
moisture content; w = 12% = 0.12
Specific gravity of soil solids; G_s = 2.72
A) Formula for dry unit weight is;
γ_d = γ/(1 + w)
where γ_w is moist unit weight as;
γ_w = W/V
γ_w = 122/0.1 = 122 lb/ft³
Thus;
γ_d = 122/(1 + 0.12)
γ_d = 108.93 lb/ft³
B) Formula for void ratio is;
e = [(G_s * γ_w)/γ_d] - 1
e = [(2.72 * 122)/108.93] - 1
e = 0.56
C) Formula for porosity is;
n = e/(1 + e)
n = 0.56/(1 + 0.56)
n = 0.36
D) Formula for degree of saturation is;
S = (w * G_s)/e
S = (0.12 * 2.72)/0.56
S = 0.58
E) Volume occupied by water is gotten from;
V_w = S*V_v
where;
V_v is volume of voids = nV
V_v = 0.36*0.1
V_v = 0.036 ft³
Thus;
V_w = 0.58 * 0.036
V_w = 0.021 ft³

The current is I=12/1000, which simplifies to 0.012 amps or 12 milliamps.
Plugging these values into the equation, we get I=12/1000, which simplifies to 0.012 amps or 12 milliamps. It's important to note that the current in a circuit is dependent on the voltage and resistance in the circuit. If either of these values were to change, the current would also change accordingly. Additionally, it's important to ensure that the components in the circuit can handle the amount of current that is flowing through them to prevent damage or overheating.
Current in electric circuits refers to the flow of electric charge. It is the rate at which electric charges, typically electrons, move through a conductor. Current is measured in amperes (A) and is represented by the symbol "I".

To build the memory chip, a number of memory cells are organized in the shape of a matrix. Each row of cells represents a memory word, and all cells in a row are connected to a common line known as the word line.
The word line is driven by an address decoder. It signifies that the RAM is organized in a 64K Words wide format. The x8 indicates that each word is 8 bits long. Most computer literature expresses the size of the processor's memory in multiples of 210 (= 1024), which is abbreviated K. As a result, 65,536 memory locations are written as 64K, implying that the addressing range is 64K. We will need 8 columns and 4 rows of 16K x 1 memory chips in order to simulate 64K x 8 with 16K x 1. There is a control input CS on each chip. It is possible for that chip to take that data input or to send the data to its output line when this input is set to 1. The upper order 2 bits of the 16-bit wide address bus are decoded to provide the four chip select (CS) control signal.

(b) assume an arduino can measure 50,000 transitions per second (it can). to obtain the fastest rpm that can be possibly measured by the above incremental encoder, what resolution of the decoding should we use? 1x (single channel (a or b), single edge), 2x (single channel (a or b), both edges) or 4x (dual channel (a and b), both edges)?
Answers
To obtain the fastest RPM measurement, the 4x (dual channel (A and B), both edges) decoding resolution should be used, as it allows the Arduino to measure 200,000 transitions per second.
To determine the fastest RPM that can be measured by the incremental encoder with the given Arduino measuring 50,000 transitions per second, we will consider the decoding resolutions 1x, 2x, and 4x:
1. 1x (single channel (A or B), single edge) - In this mode, the Arduino measures transitions on only one channel and one edge, so the maximum transitions per revolution remain the same (50,000 TPS).
2. 2x (single channel (A or B), both edges) - With both edges measured, the Arduino can detect 2 transitions per pulse. Therefore, the maximum transitions per revolution are doubled (100,000 TPS).
3. 4x (dual channel (A and B), both edges) - In this mode, the Arduino measures transitions on both channels and both edges, effectively quadrupling the transitions per revolution (200,000 TPS).

Answers
The computational complexity of one complete iteration of the K-means algorithm is O(nKd), and the complexity of step 2.1 in the K-Medoids algorithm is O(nK). The complexity of step 2.2 in the K-Medoids algorithm is O(ndK).
How to compute the complexity?The computational complexity of the K-Means algorithm for one complete iteration can be analyzed as follows:
Step 2.1: Assigning each data point to the closest representative has a complexity of O(nK), where n is the number of data points and K is the number of clusters. For each data point, we compute the distance to each representative and assign it to the closest one.
Since we have n data points and K representatives, the complexity is O(nK).
Step 2.2: Finding the best representatives given the assigned data points has a complexity of O(ndK), where n is the number of data points, d is the dimensionality of the data points, and K is the number of clusters. We consider each representative and evaluate the cost of selecting a different data point as a representative.
For each representative, we iterate over n data points and compute the distance, resulting in a complexity of O(nd). Since we have K representatives, the overall complexity is O(ndK).
Therefore, the computational complexity for one complete iteration of the K-Means algorithm is O(nK + ndK) = O(nK(d + 1)).
Moving on to the K-Medoids algorithm:
Step 2.1: Assigning each data point to the closest representative has a complexity of O(nK), similar to K-Means.
Step 2.2: Finding the best representative given the assigned data points has a complexity of O(nK), where n is the number of data points and K is the number of clusters. Unlike K-Means, K-Medoids directly selects one of the assigned data points as the representative. Hence, the complexity is O(nK).
Therefore,
the complexity of step 2.2 in K-Medoids is O(nK).
In summary:
Complexity of step 2.1 in K-Means: O(nK)
Complexity of step 2.2 in K-Means: O(ndK)
Complexity of step 2.1 in K-Medoids: O(nK)
Complexity of step 2.2 in K-Medoids: O(nK)

If the pulse air volumetric flow rate is 0.5% of the filter airflow rate and the pulse air pressure is 6.0 atm, calculate the power drawn by a 50% efficient compressor (in kW).
Answers
Answer:
1) 4.41 * 10^-4 kw
2) 2.20 * 10^-4 kw
Explanation:
Given data:
Filter = 500 m^3/min
dust velocity = 3g/m^3
bag ; length = 3 m , diameter = 0.13 m
change in pressure = 1 kPa
efficiency = 60%
1) Calculate the Fan power
First :
Calculate the total dust loading = 3 * 500 = 1500 g
To determine the Fan power we will apply the relation
\(n_{o} = \frac{\frac{p}{eg*Q*h} }{1000}\) = \(\frac{\frac{p}{(3*10^{-3})* 981*( 500/60) *3 } }{1000}\)
fan power ( \(n_{0}\) ) = 4.41 * 10^-4 kw
2) calculate power drawn
change in P = 6 atm = 6 * 10^5 pa
efficiency compressor = 50%
hence power drawn = 4.41 * 10^-4 kw * 50% = 2.20 * 10^-4 kw
