(a)
Interpretation:
To prove that
Concept Introduction:
Using,
By Joule Thompson inversion curve,
Then applying it to General equation which is given as,
(a)
Answer to Problem 7.13P
For a given Tr, we can find q and then use equation (B) to find
The Equation (A) we can find Z and then Pr with equation (C)
Explanation of Solution
We get,
Now,
Substituting
Combing these two equations yields:
The general equation is as follows,
With Van der Waals parameters becomes:
Multiply the above equation by V/RT,
substitute Z = PV/RT and
Assume,
Differentiating the above equation, we get
By
Then,
In addition,
Substitute for the two partial derivatives in the boxed equation:
hence,
Now,
(I)
(II)
Division of (II) by (I) gives
For a given Tr, we can find q and then use equation (B) to find
The Equation (A) we can find Z and then Pr with equation (C)
(b)
