Air, modeled as an ideal gas, is compressed at steady state from
1 bar, 300 K, to 5 bar, 500 K, with 190 kW of power input. Heat
transfer occurs at a rate of 25.33 kW from the air to cooling water
circulating in a water jacket enclosing the compressor.
Neglecting kinetic and potential energy effects, determine the mass
flow rate of the air, in kg/s.
