(a)
Interpretation:
Entropy change of the gas for given steady state flow process at atmospheric pressure should be determined.
(a)
Answer to Problem 5.28P
Explanation of Solution
Given information:
When
And entropy of process at constant pressure is calculated by following formula,
where
And values of constants for ethylene in above equation are given in appendix C table C.1 and noted down below:
For final temperature,
Where
and
Put the values
Hence final temperature is:
Now, the entropy change is:
Therefore entropy change is
(b)
Interpretation:
Entropy change of the gas for given steady state flow process at atmospheric pressure should be determined.
(b)
Answer to Problem 5.28P
Explanation of Solution
Given information:
When
And entropy of process at constant pressure is calculated by following formula,
where
And values of constants for1-butene in above equation are given in appendix C table C.1 and noted down below:
For final temperature,
Where
and
Put the values
Hence, final temperature is
Now, the entropy change is:
Therefore entropy change is
