Answer:

The entropy change of nitrogen during this process. is - 0.32628 kJ/K.

Explanation:

Solution

Given that:

A piston cylinder device contains =0.78 kg of nitrogen gas

Temperature = 37°C

The  nitrogen gas constant of R = 0.2968 kJ/kg.K

At room temperature cv = 0.743 kJ/kg.K

Now,

We assume that at specific condition the nitrogen can be treated as an ideal gas

Nitrogen has a constant volume specific heat at room temperature.

Thus,

From the polytropic relation, we have the following below:

T₂/T₁ =(V₁/V₂)^ n-1 which is,

T₂ = T₁ ((V₁/V₂)^ n-1

= (310 K) (2)^1.3-1 = 381.7 K

So,

The entropy change of nitrogen is computed as follows:

ΔSN₂ = m (cv₁ avg ln T₂/T₁ + ln V₂/V₁)

= (0.78) ((0.743 kJ/kg .K) ln 381.7 K/310K + (0.2968 kJ/kg. K) ln (0.5))

= 0.57954 * 0.2080 +  (-0.2057)

= 0.12058 + (-0.2057) = -0.32628

Therefore the entropy change of nitrogen during this process. is - 0.32628 kJ/K.

A lighthouse casts a 3636-foot-long shadow. Zara stands 44 feet tall and casts a 33-foot-long shadow. Since the angle to the sun is the same in both triangles, they are comparable. The height of lighthouse is 48 feet.

The polygonal shape of a triangle is made up of three edges and three vertices. It belongs to the fundamental geometric shapes. Any three points in Euclidean geometry that are not parallel identify a distinct triangle and a distinct plane simultaneously (i.e. a two-dimensional Euclidean space). In other words, each triangle is contained in a plane, and there is only one plane in which all triangles are contained. If geometry is the Euclidean plane, then all triangles are contained in a single plane, however in higher-dimensional Euclidean spaces, this is no longer the case. This article focuses on triangles in the Euclidean plane and general Euclidean geometry, unless otherwise specified.

From the question, we can see that two triangles are similar.

So, \(\frac{4}{3}=\frac{x}{36}\)

So, \(x=48\) feet.

So, The height of lighthouse is \(48\) feet.

The ratio of maximum volume to minimum volume in a cylinder is known as the aspect ratio.

The aspect ratio refers to the comparison between the maximum volume and the minimum volume within a cylinder. It is determined by dividing the maximum volume by the minimum volume. The maximum volume corresponds to the cylinder's capacity when it is completely filled, while the minimum volume represents the capacity when the cylinder is nearly empty.

The aspect ratio provides insight into the shape and proportionality of the cylinder. It is a useful measure to understand the elongation or compression of the cylinder's volume. By examining the aspect ratio, one can gain information about the relative sizes and capacities at different states of the cylinder.

If the fluid flow is supposed to be fully developed, which means that the velocity distribution doesn't change over time or space along the pipe.

Due to the no-slip condition, the fluid velocity in a pipe increases from zero at the surface to its maximum in the middle.

For a fully developed laminar viscous flow via a spherical tube, the average velocity is doubled. Remember that the maximum velocity is equivalent to (3/2) times for fully developed laminar flow through parallel plates.

To determine the smallest value of load resistance that can be used with the filter components in part e while maintaining the cutoff frequency within a 5% difference from the unloaded filter, we need to consider the impact of the load resistance on the filter's characteristics.

The cutoff frequency of a filter is primarily determined by the values of the passive components, such as resistors and capacitors, used in the circuit. The load resistance, however, can affect the filter response by introducing additional loading and altering the impedance characteristics.

In order to maintain the cutoff frequency within a 5% difference, it is generally recommended to keep the load resistance much larger than the output impedance of the filter. This helps to minimize the loading effect and maintain the desired filter response.

The specific value of the load resistance will depend on the design parameters, component values, and desired cutoff frequency of the filter in part e. Without knowing the specific details of the circuit, it is not possible to determine the exact value of the load resistance in this case. Detailed analysis and calculations based on the circuit's specifications would be required to determine the smallest load resistance value while meeting the given criteria.

Answer:

For unfined package = 1.30 × 10^-3 W.

Dor fined package = 8.64 × 10^-3 W.

Explanation:

STEP ONE: The first thing to do is to determine the cross sectional area and input the value into the convectional resistance formula/equation in order to determine the heat rate for the unfined package.

Thus, Area = (dimension of the electronic device) ^2. = (10 × 10^-6)^2 m.

Convectional Resistance = (100 × 10^-9)÷ (10 × 10^-6)^2 × 490 = 2.04 K/W.

Heat transfer coefficient = 1/ (10 × 10^-7)^2 × 10^5. = 1 × 10^5 K/W.

Thus, the heat rate for the unfined package = 2{(85 - 20) ÷ (10^5 + 2.04)} = 1.30 × 10^-3 W.

STEP TWO: Determine the surface area of each fin and the prime area.

Surface area of each fin = {300 + 15/4} × 10^-9 × 10^-9 × π × 15 = 1.43 × 10^-14 m^2.

Prime area = (10^-6 × 10)^2 - (200 × 200) × π × [ ( 15 × 10^-9)^2 ÷ 4] = 9.29 × 10^-11 m^2.

STEP THREE: Determine the efficiency

G ={ [300 + 15/4) × 10^9 } × [ 4 × 10^5÷ 490 × 15 × 10^-9] = 7.09 × 10^-2.

Efficiency= tanh ( 7.09 × 10^-2) ÷ 7.09 × 10^-2 = 0.998.

Thus, the coefficient = 1 - (1.43 × 10^-14 × (200 × 200) ÷ (6.65 × 10^-10) × (1 - 0.998) = 0.99.

STEP FOUR: Determine the heat rate for the finned package.

Thermal resistance = 1/ (10^5 × 0.999 × 10^-10 × 6.65 = 1.50 × 10^4 K/W.

The heat rate for the finned package = 2 { 85 - 20} ÷ { 1.50 × 10^4 + 2.04} = 8.64 × 10^-3 W

This happens as a result of a gain in kinetic energy at the expense of a decrease in enthalpy brought on by gas expansion as air passes through the diverging region of the nozzle.

A nozzle is a tool used to change the characteristics of a fluid flow as it leaves a confined chamber or conduit, particularly to enhance velocity. The reciprocal of the nozzle length, pressure, and the square root of the nozzle diameter all increase air velocity.

A nozzle needs to be made to expand steam from 500 PA at 210 °C to 100 kPa at a rate of 0.1 kg/s.  In order to reach critical or sonic conditions (i.e., choked flow) at its throat, the flow is accelerated when a nozzle is used.

Therefore, The steam's specific volume at the nozzle's exit is determined to be 1.4 m3/kg and its velocity at that point to be 700 m/s.

Sodium hydroxide, NaOH, is a very useful compound in the chemical industry. Sodium hydroxide is used to make soap, detergent, paper, and many other products. It is also used to clean drains, dissolve grease, and other materials.

For commercial convenience, one form of sodium hydroxide that is sold commercially is the saturated solution. This solution is M, which is approximately by mass sodium hydroxide.

To prepare L of M solution, we must first find the number of moles of NaOH that will be required.

Then we will find the volume of the saturated solution that is required to make this solution.
To find the number of moles of NaOH that will be required, we will use the formula:

\(N = C x V\)Where, N = number of moles of NaOH, C = concentration of the solution, and V = volume of the solution.

In this case, C = M, which is the concentration of the solution that we want to make. And V = L, which is the volume of the solution that we want to make.

So,

\(N = M x LV = N / MC = 40% = 40 / 100 = 0.4 M\)

Volume of the saturated solution required to prepare the M solution:

\(V = N / MV = 4.69 L\)

We will require approximately \(4.69 L\)of the saturated solution to prepare L of M solution.

The problem requires counting the number of strings in an array that have a given length. To solve this problem, we can iterate through the array of strings and check the length of each string against the target length. If the length matches, we can increment a counter variable.

Here's an implementation of the solution in Python:

def wordsCount(words, length):

   count = 0

   for word in words:

       if len(word) == length:

           count += 1

   return count

In this solution, we first initialize a counter variable count to zero. Then, we loop through each element in the words array and check if its length is equal to the target length. If the length matches, we increment the count variable. Finally, we return the count value.

In the input array ["a", "bb", "b", "ccc"] and target length 1, the function will count the number of strings with length 1, which is 2. Similarly, for target length 3, the function will return 1. And for target length 4, the function will return 0.

The tensile stress on the bolt is 78.29 MPa.

What Exactly Is Tensile Stress?

Tensile stress () is an object's resistance to a force that may rip it apart. It is measured in Newtons/mm2, but was formerly denoted in tons/inch2. It is computed with the maximal strain endured by the object in question without tearing. Tensile stress is defined as the magnitude of force applied along an elastic rod divided by the cross-sectional area of the rod perpendicular to the applied force.

T = C_t x D x sigma x A_s

tensile stress = sigma = T/(C_t x D x A_s)

A_s = (pi/4)x(D - 0.9382xp) ^2

D = 12mm <-- diameter

p = 1.75 <-- pitch

C_t = 0.24 <-- torque coefficient

T = 19000 N-mm <-- torque

A_s = (pi/4)x(12 - 0.9382x1.75)^2 = 84.3 mm^2
