5.7 kg/s of saturated water steam enters a compressor with a pressure equal to 100 kPa and leaves it at a pressure equal 2.5 MPa and enthalpy equal to 3009.6 kJ/kg . The thermal losses towards the environment, due to an old insulation, amount to 0.2 MW. Due to friction, the compressor has a mechanical efficiency=0.94. Determine the mechanical power in MW (1 decimal place) requested by the compressor.
