Air is expanded isentropically from a reservoir in which the pressure is 1000 kPa to a pressure of 150 kPa. A normal shock occurs at this point in flow. Find the pressure downstream of the shock wave.

The rate of heat transfer by convection is approximately 2.01 kW.

The rate of heat transfer by convection (kW) when the convective heat transfer coefficient is 7.2 W/Km²,

the surface area is 16 m²,

the surface temperature is 317 K, and

the surrounding temperature is 429 K is approximately 2.01 kW.

Let's see how to obtain this result. Basically, we have to find the rate of heat transfer by convection, which is given by this equation:

\(q = hA(Ts − T∞)\)

where q is the rate of heat transfer by convection,

h is the convective heat transfer coefficient,

A is the surface area,

Ts is the surface temperature, and

T∞ is the surrounding temperature.

Now, substitute the given values and compute the result:

\(q = (7.2 W/Km^2) × (16 m^2) × (317 K − 429 K)q ≈ - 2.01 kW\)

Therefore, the rate of heat transfer by convection is approximately 2.01 kW.

a)The equation of the elliptical cross section if the origin of a rectangular coordinate system is placed at one of the covertices can be obtained by using the standard form of the equation of an ellipse: x²/a² + y²/b² = 1.

Since the origin is at one of the covertices, the center of the ellipse is located at (0, 0) and the major axis of the ellipse coincides with the horizontal axis. Therefore, the horizontal opening of the ellipse corresponds to the length of the major axis, which is 4 feet, and the vertical opening of the ellipse corresponds to the length of the minor axis, which is 3 feet. Thus, we have:a = 4/2 = 2b = 3/2 = 1.5Therefore, the equation of the elliptical cross section is:x²/4² + y²/1.5² = 1Here is the sketch of the ellipse with the origin at one of the covertices: b)The foci of the ellipse can be found by using the formula c = √(a² - b²),

where c is the distance between the center of the ellipse and each focus. In this case, we have:a = 2b = 1.5Therefore:a² = 4b² = 2.25c = √(a² - b²) = √(4b² - b²) = b√3 ≈ 1.3Thus, the foci of the ellipse are located at (±c, 0), that is, at (±1.3, 0).Here is the sketch of the ellipse with the foci marked in red: c)The eccentricity of the ellipse can be obtained by using the formula e = c/a. In this case, we have:a = 2c = b√3 ≈ 2.6Therefore:e = c/a = (b√3)/2 ≈ 0.65Thus, the eccentricity of the ellipse is approximately 0.65.

Technician A: Plastic repair adhesives may be applied over paint.

- This is partially true. Plastic repair adhesives can adhere to painted surfaces, but the adhesion may not be as strong as on bare plastic. The paint layer can affect the adhesion and bonding of the adhesive.

Technician B: Melted plastic may cause poor adhesion to the plastic repair adhesives.

- This is true. If the plastic is melted or damaged before applying the repair adhesive, it will not provide a good surface for the adhesive to bond to. Melted, softened or degraded plastics will not adhere well to repair adhesives designed for plastics. The adhesive needs a clean, intact plastic surface to effectively bond to.

In summary:

- Plastic repair adhesives can work on painted plastics but adhesion may be compromised.

- Severely damaged, melted or degraded plastics will not provide good adhesion for plastic repair adhesives.

- For the strongest bond, plastic repair adhesives should be applied to clean, intact plastic surfaces.

So both technicians provided partially correct information, but Technician B identified an important limitation - that melted or damaged plastics will not adhere well to plastic repair adhesives. Proper surface preparation and condition are key to effective adhesion.

Explanation:

The mass of the liquid is 61.029 N. The mass of the liquid is 60.636 N in the second scenario.

The density of a solid, liquid, or gas describes how closely packed the particles are. Density is defined as the amount of mass per unit volume.

The mass of a liquid can be calculated using its volume and density. The formula is:

mass = density x volume

We are given the density of the unknown liquid as 12400 N/m³ and the volume as 500 cm³.

We need to convert the volume from cm³ to m³ before we can use the formula:

500 cm³ = 0.0005 m³

(a) Using the standard value of gravity (9.81 m/s²):

mass = density x volume x gravity

= 12400 N/m³ x 0.0005 m³ x 9.81 m/s²

= 61.029 N

Therefore, the mass of the liquid is 61.029 N.

(b) Using the minimum value of gravity on Earth (9.78 m/s²):

mass = density x volume x gravity

= 12400 N/m³ x 0.0005 m³ x 9.78 m/s²

= 60.636 N

Therefore, the mass of the liquid is 60.636 N.

(c) Using the maximum value of gravity on Earth (9.83 m/s²):

mass = density x volume x gravity

= 12400 N/m³ x 0.0005 m³ x 9.83 m/s²

= 61.422 N

Thus, the mass of the liquid is 61.422 N.

Replace test.txt with the path to your test file. The program will display the total number of words or the number of unique words, depending on the specified mode using the -t or -u options, respectively.

Here's the modified code that incorporates the required functionality:

#include <iostream>

#include <vector>

#include <string>

#include <getopt.h>

using namespace std;

int main(int argc, char** argv) {

   enum { total, unique } mode = total;

   for (int c; (c = getopt(argc, argv, "tu")) != -1;) {

       switch(c) {

           case 't':

               mode = total;

               break;

           case 'u':

               mode = unique;

               break;

       }

   }

   argc -= optind;

   argv += optind;

   string word;

   int count = 0;

   vector<string> words;

   while (cin >> word) {

       words.push_back(word);

       count++;

   }

   switch (mode) {

       case total:

           cout << "Total: " << count << endl;

           break;

       case unique:

           cout << "Unique: " << words.size() << endl;

           break;

   }

   return 0;

}

This code reads words from the input and stores them in a vector<string> called words. The variable count keeps track of the total number of words read. When the -u option is provided, the size of the words vector is used to determine the number of unique words.

To compile and run the program, use the following commands:

bash

Copy code

g++ words.cpp -o words

Answer:

minimum volume = 367.5 lit

minimum weight = 228.75 kg

Answer:

A) condenser pressure = 9.73 kPa,

B) 10242 kw

C) 36.9%

Explanation:

given data

entrance pressure of steam = 12.5 MPa

temperature of steam = 550⁰c

flow rate of steam = 7.7 kg/s

outer pressure = 2 MPa

reheated steam temperature = 450⁰c

isentropic efficiency of turbine( nt ) = 85% = 0.85

isentropic efficiency of pump = 90% = 0.90

From steam tables

at 12.5 MPa and 550⁰c ; h3 = 3476.5 kJ/kg,  S3 = 6.6317 kJ/kgK

also for an Isentropic expansion

S4s = S3 .

therefore when S4s = 6.6317 kJ/kg and P4 = 2 MPa

h4s = 2948.1 kJ/kg

nt = 0.85

nt (0.85) = \(\frac{h3-h4}{h3-h4s}\) = \(\frac{3476.5 - h4}{3476.5 - 2948.1}\)

making h4 subject of the equation

h4 = 3476.5 - 0.85 (3476.5 - 2948.1)

h4 = 3027.3 kj/kg

at P5 = 2 MPa and T5 = 450⁰c

h5 = 3358.2 kj/kg,  s5 = 7.2815 kj/kgk

at P6 , x6 = 0.95  and s5 = s6

using nt = 0.85 we can calculate for h6 and h6s

from the chart attached below we can see that

p6 = 9.73 kPa, h6 = 2463.3 kj/kg

B) the net power output

solution is attached below

c) thermal efficiency

thermal efficiency = 1 - \(\frac{qout}{qin}\) = 1 - ( 2273.7/ 3603.8) = 36.9% ≈ 37%

The correct answer is since the counters can more easily quantify 20 than 1, timing many oscillations reduces the likelihood of inaccuracy in respect of inertial balance.

What is the purpose of inertial balance?

To determine an object's mass using an inertial balance. This inertial balance kit is primarily intended for use in a lab experiment where mass is quantitatively measured apart from the gravitational pull of the Earth to illustrate Newton's First Law. The mass of an object in a weightless environment is frequently calculated in space missions using the same technique.

The kit consists of a frame with two platforms, one of which has holes, joined by two horizontal spring blades. Three cylinders of unknown mass with shoulders are also included; they can all be inserted into the platform's holes. One of these masses has a hole that enables it to be suspended from a ring stand or other object using string (included).

Hence, due by timing more than one oscillation, it lessens the possibility of error, in that the counters have an easier time quantifying 20 versus 1.

Answer:

the magnitude of the stress necessary to cause slip to occur on the (111) plane in the \([1 0 \overline 1]\) direction is 4.85 MPa

Explanation:

From the given information;

To determine the angle \(\phi\) between the direction [100] and [111]; we have:

\(\phi = cos ^{-1} [\dfrac{u_1u_2+v_1v_2+w_1w_2}{ \sqrt{(u_1^2+v_1^2+w_1^2) (u_2^2+v_2^2+w_2^2) }}}\)

where;

[u₁,v₁,w₁] and [u₂, v₂, w₂] are directional indices.

replacing 1 for u₁ , 0 for v₁ and 0 for w₁  ;

also replacing 1 for u₂, 1 for v₂ and  1 for w₂ ; we have :

\(\phi = cos ^{-1} [\dfrac{1*1+0*1+0*1}{ \sqrt{(1^2+0^2+0^2) (1^2+1^2+1^2) }}}\)

\(\phi = 54.7^0\)

To determine the angle \(\lambda\) for the slip direction \([1 0 \overline 1]\)

\(\lambda= cos ^{-1} [\dfrac{u_1u_2+v_1v_2+w_1w_2}{ \sqrt{(u_1^2+v_1^2+w_1^2) (u_2^2+v_2^2+w_2^2) }}}\)

replacing 1 for u₁ , 0 for v₁ and 0 for w₁  ;

also replacing 1 for u₂, 1 for v₂ and  -1 for w₂ ; we have :

\(\lambda = cos ^{-1} [\dfrac{1*1+0*0+(0*-1)}{ \sqrt{(1^2+0^2+0^2) (1^2+0^2+(-1^2)) }}}\)

\(\phi = cos ^{-1} [\dfrac{1}{\sqrt{2}}]\)

\(\lambda = 45^0\)

The yield strength  for the slip process \([1 0 \overline 1]\) can now be calculated as:

\(\sigma_x = \dfrac{t_{xr}}{cos \phi \ \ cos \lambda}\)

where

\(t_{xr}\) = 1.98 MPa

\(\sigma_x = \dfrac{1.98}{cos 54.7^0 \ \ cos 45}\)

\(\sigma_x = \dfrac{1.98}{0.5779 *0.7071}\)

\(\mathbf{\sigma _x = 4.85 \ MPa}\)

Hence, the magnitude of the stress necessary to cause slip to occur on the (111) plane in the \([1 0 \overline 1]\) direction is 4.85 MPa
