470 kg/h of steam drives a turbine. The steam enters the turbine at 44 atm and 450oC at a linear velocity of 55 m/s and leaves at a point 5 m below the turbine inlet at atmospheric pressure and a velocity of 375 m/s. The turbine delivers shaft work at a rate of 70 kW, and the heat loss from the turbine is estimated to be 104 kcal/h.
Gravitational acceleration = 9.81 kg/m2
Determine the potential energy (W) associates with this process.
