An insulated turbine operating at steady state develops 20 MW of power at steam flow rate of 1,500 kg/min. H2O enters the turbine at 2.5 MPa with a velocity of 40 m/s, and it exits at saturated vapor state at 5 kPa with a velocity of 200 m/s. Please determine the inlet temperature. The effect of potential energy can be neglected. Employ interpolation if needed
