Answer:
The work done or the heat transfer for air and hydrogen are 91.71 kj/kg and 1317.89 kj/kg respectively.
Explanation:
Given:
Initial pressure is 7.6 bar.
Initial temperature is 77 °C.
Final pressure is 3.05 bar.
Calculation:
(a)
Take air as an ideal gas with gas constant 0.287 kj/kgK.
Step1
For isothermal process work done and heat transfer is the same because of no change in internal energy.
Work done is calculated as follows:
W = 91.71 kj/kg.
Thus, the work done or the heat transfer for isothermal process is 91.71 kj/kg.
Step2
For isothermal process work done and heat transfer is the same because of no change in internal energy. Take Hydrogen as an ideal gas with gas constant 4.1242 kj/kgK.
Work done is calculated as follows:
W = 1317.89 kj/kg.
Thus, the work done or the heat transfer for isothermal process is 1317.89 kj/kg.
Assume that the antenna absorbs all the radiation that falls on the disk and calculate the power in Watts received by the antenna are the (a) 3.0e-8.

What is perpendicular with examples?</h3>
Two awesome traces intersecting every different at 90° or a proper perspective are referred to as perpendicular traces. Here, AB is perpendicular to XY due to the fact AB and XY intersect every different at 90°. The traces are parallel and do now no longer intersect every different. They can in no way be perpendicular to every different.

Answer:
%Program prompts user to input vector
v = input('Enter the input vector: ');
%Program shows the value that user entered
fprintf('The input vector:\n ')
disp(v)
%Loop for checking all array elements
for i = 1 : length(v)
%check if the element is a positive number
if v(i) > 0
%double the element
v(i) = v(i) * 2;
%else the element is negative number.
else
%triple the element
v(i) = v(i) * 3;
end
end
%display the modified vector

Answer:
Simply put, the grade or grading around your house is the level of the ground. The ground level and how it's graded is the deciding factor of where storm water will flow.
