Refrigerant-134a enters an adiabatic compressor at 100 kPa and –24°C with a flow rate of 1.3 m3/min and leaves at 800 kPa and 60°C. Determine the mass flow rate of R-134a and the power input to the compressor. Use data from the steam tables. Heat transfer with the surroundings is negligible. Neglect kinetic and potential energy changes.
