Prоblem 1 (30 pts)  The figure belоw illustrаtes а vаpоr compression cycle using R134a as the working fluid.  The properties at each of the states in the cycle are provided in the table.  The saturation properties of R134a (analogous to Table B-1 in your water tables) are also provided below. Properties at each state in the cycle: Saturation Properties of R134a: The cycle provides refrigeration to a cold space at TC = -10°C (263.2 K) and rejects heat to ambient at TH = 20°C (293.2 K).  The displacement rate of the compressor is 0.006 m3/s and the cycle provides 6 kW of cooling in the evaporator. a.) What is the mass flow rate of refrigerant in the cycle (kg/s)?
