For air properties use online source: https://www.peacesoftware.de/einigewerte/luft_e.html

The compressor is operating at steady-state increasing pressure of R-22 refrigerant from 4 bars to 14 bars. Temperature was rising during the process from 12C to 90C. The inlet volumetric flow rate is 1 m³/min and inlet diameter is 0.03m. At the exit the diameter is the same. Heat flow to the surroundings can be neglected. Determine:

a.Mass flow rate [kg/s]

b. Inlet and outlet velocity [m/s]

c.Power required to run the compressor [kW]
