1. An inventor reports that she has a refrigeration compressor that receives saturated Refrigerant-134a vapor at 0.00°F and delivers it at 150. psia and 120.°F. The compression process is adiabatic. Determine whether or not this process violates the second law of thermodynamics.
2. A 1.00 MW steam power plant operates on the simple reversible thermodynamic cycle shown Figure 9.23.
a. What is its thermal efficiency?
b. What is the steam mass flow rate in this system?
c. What is its thermal efficiency if it is operated on a Carnot cycle?
