A spherical container of inner radius of 0.44 m and outer radius of 0.6 m with a thermal conductivity 18 W/m·K holds radioactive

waste that generates heat at 1 x 105 W/m3. The outer surface is exposed to a water flow with [infinity] 25°C and 750 W/m2·K. Find the heat transfer through the wall of container as well as the temperatures at the inside and outside surfaces of the container

Answer:

Explanation:

The concept of heat transfer is applied, by first equation the heat generated to the heat trasnfer by convection to get the temperature of the outer surface.

Also equating the head conducted to the heat generated to get the temperature of the inside surfaces. Tthe steps and detailed calculations is as shown in the attachment.

Part of the following pseudocode is incompatible with the Java, Python, C, and C++ language Identify the problem. How would you
hammer [34]

Answer:

The main problem is the incorrect use of assignment operator, the correct way to check if two number are equal is

num1==num2

Explanation:

Here we have a created a simple function which takes two input arguments num1 and num2. In the body of the function we have used if condition to find out whether the two number are equal or not. If condition is true then print that values are equal. If condition is false then print that values are not equal. In the driver code, we have called the function two times with different values of num1 and num2 to check if it is working correctly.

The implementation logic is same in all these programming languages, the only difference the syntax.

Python Code:

def checkEquality(num1, num2):

   if num1 == num2:

       print("The values are equal.")

   else:

       print("The values are not equal.")

Driver Code:

checkEquality(2,5)

checkEquality(3,3)

Output:

The values are not equal.

The values are equal.

C++ Code:

void checkEquality(int num1, int num2) {

   if (num1 == num2)

       cout<<"The values are equal."<<endl;

   else

       cout<<"The values are not equal."<<endl;

}

Driver Code:

#include <iostream>

using namespace std;

void checkEquality(int num1, int num2);

int main()

{

checkEquality(2,5);

checkEquality(3,3);

return 0;

}

Output:

The values are not equal.

The values are equal.

In the construction of a large reactor pressure vessel, a new steel alloy with a plane strain fracture toughness of 55 MPa-m1/2
sp2606 [1]

Answer:

l=24mm

Explanation:

From the question we are told that:

Plane strain fracture toughness of T=55 MPa-m1/2

Y value Y=1.0

Stress level of\sigma =200 MPa

Generally the equation for length of a surface crack is mathematically given by

l=\frac{1}{\pi}(\frac{T}{Y*\sigma})^2

l=\frac{1}{3.142}(\frac{55}{1*200})^2

l=0.024m

Therefore

in mm

l=24mm

To measure the voltage drop across a resistor, a _______________ must be placed in _______________ with the resistor. Ammeter; S
gulaghasi [49]

Answer:

The given blanks can be filled as given below

Voltmeter must be connected in parallel

Explanation:

A voltmeter is connected in parallel to measure the voltage drop across a resistor this is because in parallel connection, current is divided in each parallel branch and voltage remains same in parallel connections.

Therefore, in order to measure the same voltage across the voltmeter as that of the voltage drop across resistor, voltmeter must be connected in parallel.

What does this middle button on the middle of my Chevrolet equinox steering wheel mean?
almond37 [142]

Answer:

Depending on how new your vehicle is, to me it looks like some sort of turn on button for forward collision safety feature, but i'm not an expert with this particular vehicle. If you want a better answer, I strongly suggest looking at the owner's manual under which should be located in the front dash compartment on the passengers side. Once you have the manual, look in the appendix until you find controls (or something similar) then go to that page and read about your vehicles control buttons. Your answer should be in the manual.

Something that all automobile owners should do right after purchasing a new vehicle, is reading the owners manual. As boring as it may seem, reading the owner's manual will help you get used to your new car quicker and give you instructions on how to take care of your car so that it lasts.

Have a great day, and I wish you safe traveling for now and forever! :)
