Spring 2006 1 ME 201 Thermodynamics Homework 14, Due Wednesday, 3/22/2006 1. Consider the Carnot cycle occurring in a piston-cylinder device containing refrigerant-134a with operating conditions given below: Process A: Isothermal heat addition at T H = 30 ° C to convert saturated liquid to saturated vapor Process B: Isentropic and adiabatic expansion to T
