An ideal vapor-compression refrigeration cycle opperates at steady state with refrigeratn 134a as the working fluid. Saturated vapor enters at the compressor at 2 bar, and saturated liquid exits the condenser at 8 bar. The mass flow rate of refrigerant is 7kg/min
Determine:
a) the compressor power in KW
b)the refrigerating capacity in tons
c)the coefficient of performance.
