Following the process used in Example 5.5, develop an expression for the change in the dependent variable h in terms of the independent properties T and s, that is, h = h1T,s 2. Write your answer using cp, b, k, and v. Consider an isentropic expansion process. Determine how h changes with T.

Example 5.5

Use Equations (5.40) and (5.41) to develop an expression for s = s(Tv) in terms of CP, B, K, and v. From the relationship that is developed, determine a general relationship for Cp Co.
