The denity of a certain type of jet fuel i 775 kg/m3. Determine it pecific gravity and pecific weight
Answers
The correct answer is Specific weight: w = [weight ÷ volume] = [9N ÷ 0.001m³] = 9000N/m³Density: w = [ × g] Where, g = acceleration due to gravity = 9.81m/sec². Specific gravity: G = [density of liquid ÷ density of water] As you know, The density of water = 1000kg/m³.
The density of a substance is divided by the density of water at 4 degrees Celsius to determine its specific gravity. The density of the substance and the density of the water must be represented in the same units for the calculation.distinguishes While specific weight has dimensions, specific gravity is a dimensionless number. The gravitational field has no effect on a material's specific gravity, but it does have an effect on a material's specific weight. A substance's "Specific Gravity" is determined by dividing its mass by the mass of an equivalent volume of water at the same pressure and temperature.

A small family home in Tucson, Arizona, has a rooftop area of 1967 square feet, and it is possible to capture rain falling on about 56% of the roof. A typical annual rainfall is about 14 inches. If the family wanted to install a tank to capture the rain for an entire year, without using any of it, what would be the required volume of the tank in m3 and in gallons? How much would the water weigh when the tank was full (in N and in lbf)?
Answers
Answer:
V = 36.4 m³ = 4.86 gallons
W = 80193.88 lbf = 356720 N = 356.72 KN
Explanation:
We have the following data given in the question:
At = Total area of roof = 1967 ft²
h = Annual Rainfall = 14 inches = 1.17 ft
V = Volume of tank in m³ and gallons = ?
W = Weight of water in N and lbf = ?
So, for volume we know that the area of roof that receives rainfall is 56% of total area and 14 inches of annual rainfall means that there is a standing height of 14 inches of rain water for a given area, for 1 year.
Area to receive rain = A = 0.56*1967 ft² = 1101.52 ft²
Now,
Volume = V = A * h = 1101.52 ft²)(1.17 ft)
V = 1285.11 ft³
Converting to m³:
V = (1285.11 ft³)(1 m³/35.3147 ft³)
V = 36.4 m³
Converting to gallons:
V = (1285.11 ft³)(1 m³/264.172 gal)
V = 4.86 gal
Now, for the weight of water, we use formula:
W = ρVg
where,
W = weight of water = ?
ρ = Density of water = 1000 kg/m³
V = Volume of tank = 36.4 m³
g = 9.8 m/s²
Therefore,
W = (1000 kg/m³)(36.4 m³)(9.8 m/s²)
W = 356720 N = 356.72 KN
Converting to lbf:
W = (356720 N)(1 lbf/4.44822 N)
W = 80193.88 lbf
create a bar/column chart showing the total number of daily new cases over time. the chart should have a date axis and one bar per day. it means if there are 200 days in the dataset, you should have 200 bars. also, since the dataset contains three districts, your chart should aggregate the data. it means there should be one value per day equal to the sum of new cases from all three districts on that particular day. you should be able to see the trend of new cases over time from your chart. create a stacked bar/column chart showing the monthly number of new cases over time by district. one axis should be month (from 1 to 12), and the other axis is total new cases. there should be 12 bars (for 12 months), and each bar should be broken into 3 stacks. each stack shows the number for a single state. (hint: you can create a month column like what we did in hw2 before making the chart). create a line chart to show daily new cases trend by state. the chart should have one axis for date, and the other axis for daily new cases. the chart should have 3 lines. each line shows the trend of one particular state. you should be able to see the trend overtime for each state, and compare the overall performance among these 3 states. create a line chart similar to question 3, but using death case instead of new case. comparing it wtih question 3: describe the trend of new case and death case. do the new case and death case have same trend? what did you learn from these two charts? create a pie chart using 2021 total new cases and show the proportion by state. it should be one pie with three pieces. create a dashboard in a new sheet and put all above charts in the dashboard assuming you are using the dashboard as a poster to make presentation. be sure to align them well, add proper chart title, axis label, use proper color, and add dashboard title at the top.

projective tests face the same drawbacks as other b-data tests, including that
Answers
Projective tests are a type of psychological assessment tool that involve presenting individuals with ambiguous stimuli, such as inkblots or drawings, and asking them to provide interpretations or responses.
While projective tests can provide useful insights into an individual's personality or thought processes, they are not without their drawbacks.
One of the main drawbacks of projective tests, as with other "b-data" tests (behavioral data), is that they are subjective in nature and rely heavily on the interpretation of the examiner. The responses and interpretations may be influenced by the examiner's biases, and there is no clear set of guidelines or criteria for scoring or evaluating the responses. This can lead to inconsistencies and inaccuracies in the results.
Another drawback of projective tests is that they are time-consuming and resource-intensive, requiring a trained examiner to administer and interpret the results. This can make them less practical for use in large-scale assessments or in settings where resources are limited.
Additionally, some individuals may feel uncomfortable or resistant to the ambiguous stimuli presented in projective tests, which can affect their responses and the accuracy of the results.

Answers
Limpies are best used for removing shrub structural branch defects.
Limpies are specialized pruning tools commonly used in horticulture and arboriculture. They are specifically designed for the precise and careful removal of shrub structural branch defects. These defects can include broken, dead, diseased, or crossing branches that affect the overall health and aesthetics of the shrub. Limpies are equipped with sharp blades and a scissor-like action, allowing for clean and accurate cuts to be made close to the main stem or branch collar. This helps promote proper healing and reduces the risk of disease or insect infestation. While limpies can be used for general pruning tasks, they excel in addressing structural branch defects and maintaining the overall health and integrity of shrubs.

A pipe 120 mm diameter carries water with a head of 3 m. the pipe descends 12 m in altitude and reduces to 80 mm diameter, the pressure head at this point is 13 m. Determine the velocity in the small pipe and the rate of discharge (in L/s)? Take the density is 1000 kg/m³.
Answers
Given:
- Diameter of the first pipe (D1): 120 mm = 0.12 m
- Diameter of the second pipe (D2): 80 mm = 0.08 m
- Head at the first pipe (H1): 3 m
- Altitude change (Δh): 12 m
- Head at the second pipe (H2): 13 m
- Density of water (ρ): 1000 kg/m³
Step 1: Calculate the velocities in the pipes using Bernoulli's equation.
Applying Bernoulli's equation between the two points in each pipe:
For the first pipe:
P1/ρ + V1²/2g + H1 = constant (1)
For the second pipe:
P2/ρ + V2²/2g + H2 = constant (2)
Since the pipes are open to the atmosphere, we can assume P1 = P2 = atmospheric pressure (approximately).
Simplifying equation (1):
V1²/2g + H1 = constant (3)
Simplifying equation (2):
V2²/2g + H2 = constant (4)
Step 2: Solve for the velocities V1 and V2.
Using equation (3) for the first pipe:
V1²/2g + 3 = constant (5)
Using equation (4) for the second pipe:
V2²/2g + 13 = constant (6)
Step 3: Solve for the velocities V1 and V2.
Since the constants in equations (5) and (6) are the same (as it is a continuous flow), we can equate the two equations:
V1²/2g + 3 = V2²/2g + 13
V1²/2g - V2²/2g = 10
(V1² - V2²)/(2g) = 10
V1² - V2² = 20g
V1² = V2² + 20g (equation 7)
Step 4: Convert the diameter to radius for each pipe.
r1 = D1/2 = 0.12/2 = 0.06 m
r2 = D2/2 = 0.08/2 = 0.04 m
Step 5: Calculate the rate of discharge (Q) using the continuity equation.
The continuity equation states that the product of the cross-sectional area (A) and the velocity (V) is constant in a flowing fluid.
Q1 = Q2 (since it is a continuous flow)
A1V1 = A2V2
πr1²V1 = πr2²V2
(r1²V1)/(r2²) = V2
Step 6: Calculate the velocity in the smaller pipe (V2).
Substitute the values in equation (7):
V1² = V2² + 20g
(V1²r2²)/(r1²) = V2²
(0.06²V2²)/(0.04²) = V2²
V2² = (0.06²V1²)/(0.04²) [Substitute V1² = 2g(3) from equation (5)]
V2² = (0.06² × 2g × 3)/(0.04²)
V2² = 0.27g
V2 = √(0.27g)
Step 7: Calculate the rate of discharge (Q) in L/s.

Answers
The outlet temperature of both streams in steady operation of a double-pipe, parallel-flow heat exchanger will be the same as their inlet temperature, which is 120C for the tube-side stream and 20C for the other stream. This is because the logarithmic mean temperature difference is zero, indicating no temperature change during heat transfer.
To find the outlet temperature of both streams in a double-pipe, parallel-flow heat exchanger, we need to use the formula Q=U*A*ΔTlm, where Q is the heat transfer rate, U is the overall heat transfer coefficient, A is the heat transfer area, and ΔTlm is the logarithmic mean temperature difference.
First, we can calculate the logarithmic mean temperature difference using the formula ΔTlm= (ΔT1-ΔT2)/ln(ΔT1/ΔT2), where ΔT1 and ΔT2 are the temperature differences of the hot and cold streams, respectively.
ΔT1= 120-20=100C
ΔT2= 120-20=100C
ΔTlm= (100-100)/ln(100/100)= 0
Since ΔTlm=0, we can conclude that the outlet temperature of both streams will be the same as their inlet temperature. Therefore, the outlet temperature of the tube-side stream will be 120C, and the outlet temperature of the other stream will be 20C.

g a water treatment plant is being designed with a flowrate of 2.0 mgd. the plant will have two (equally sized) upflow clarifiers with a surface overflow rate of 800 gpd/ft2 and a detention time of four hours. a. what diameter is required for the clarifiers (ft)? b. what is the weir loading rate (gpd/ft)
Answers
The solution to the diameter asked in the question is 35.8 ft and the wire loading rate is 0.000011 gpd/ft. We can calculate it in the following manner.
To determine the diameter required for the clarifiers:
a. We can start by calculating the total surface area needed for both clarifiers. Since both are equally sized, we can divide the flowrate in half and use it for each clarifier:
2.0 mgd / 2 = 1.0 mgd
Convert mgd to gpd:
1.0 mgd x 1,000,000 g/mgd = 1,000,000 gpd
Calculate the surface area needed for one clarifier:
1,000,000 gpd / (800 gpd/ft2) = 1,250 ft2
Since the clarifiers are upflow, we can assume a height of about 10-12 feet. Let's use 12 feet for this calculation.
The volume of one clarifier is then:
1,250 ft2 x 12 ft = 15,000 ft3
To determine the diameter of the clarifiers, we can use the formula for the volume of a cylinder:
V = πr²h
Where V is the volume, r is the radius, and h is the height.
Solving for r:
r = √(V/πh) = √(15,000 ft3 / (π x 12 ft)) = 17.9 ft
The diameter is twice the radius, so:
diameter = 2 x 17.9 ft = 35.8 ft
b. To determine the wire loading rate, we need to calculate the total length of wire required for one clarifier, and then divide by the flow rate. We can use the equation:
Q = CLH¹°⁵
Where Q is the flow rate (gpd), C is a constant (we'll use 3.33 for rectangular wires), L is the length of the weir (ft), and H is the height of the weir (ft).
Solving for L:
L = Q / (CH¹°⁵) = 1,000,000 gpd / (3.33 x 12^¹°⁵ ft) = 5.5 ft
Since there are two clarifiers, the total length of wire required is:
2 x 5.5 ft = 11 ft
Dividing by the flow rate:
11 ft / 1,000,000 gpd = 0.000011 gpd/ft
