ChE 330 Fall 2015 HW 4 Due: Sept 24 5.1
(i) This is a standard Rankine cycle problem using steam.
This is a refrigeration cycle problem using propane (use p-H chart for propane in Appendix). 5.15 This problem is a Claude liquefaction process for methane. (Use methane p-H chart in Appendix). 6.2 (a, c, f, h, i) Here you are asked to express various derivatives in terms of certain variables (P, V, T and their derivatives and absolute S).
You may use Eqn. 6.37 - 6.41 as needed, as well as various definitions and calculus rules. 6.8 Joule-Thomson coefficient µJT is an important measurable derivative and can be used to test the validity of equations of state.
Here you are asked to express µJT using the vDW equation and the ideal gas equation. 6.10 (h) You know for ideal gas CP - CV = R. Here you are given data for ?, aP and ?T and asked to compute CP - CV. First see page 244 where the book derives (CP - CV ) for a general fluid. You express the RHS of that equation in terms of the given data, then compute the answer.
