Consider a one-inlet, one-exit control volume operating at steady state. Air enters at 200 lb/in2 , 1040◦R and expands adiabatically to 50 lb/in2 . You may assume that the air acts as an ideal gas and that changes in kinetic and potential energy effects are negligible. Determine the rate of entropy production, in Btu/8R per 1b of air flowing in following cases.
Consider the following two different cases.
a. In the first case, the control volume only encloses a turbine with an isentropic efficiency of 75%.
b. In the second case, the control volume only encloses a throttling valve.
