(a)
Interpretation:
What is the minimum power requirement in hp of air.
Concept Introduction:
The minimum power requirement is calculated by following formula if air is assumed as an ideal gas:
....(1)
(a)
Answer to Problem 5.47P
Explanation of Solution
Given information:
It is given that air at
Hence
From equation (1),
For an ideal gas
....(2)
And
Values of above constants for air in equation (2) are given in appendix C table C.1 and noted down below:
Hence
And
Therefore,
And
For an ideal isobaric gas
....(3)
And
Values of above constants for air in equation (3) are given in appendix C table C.1 and noted down below:
Hence
And
Therefore,
Hence
And we know that for an ideal gas, ideal gas law is applicable and hence
Hence
