Question:

Refrigerant R-134a enters an adiabetic compressor at 175 kPa, -10oC and leaves at 1 MPa. The mass flow rate (m⋅) is 0.02 kg/s. Using the Compressor Simulator RIA (linked from left margin).
(a) Determine the shaft power (W⋅sh) of the compressor.
(b) Plot how shaft power varies with exit pressure varying from 175 kPa to 1 MPa.
