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

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
