A steam turbine receives superheated steam at 1.4 MPa and 400°C (enthalpy h₁ = 3257.5kJ/kg). The steam leaves the turbine at atmospheric pressure (101 kPa) and 100°C (enthalpy h₂ = 2676kJ/kg). The steam enters the turbine at velocity v₁ = 15 m/s and exits at velocity v2 = 60 m/s. The heat loss through the turbine walls is 2 kW. The elevation difference between the turbine entry and exit is negligible. If the mass flow rate through the turbine is 0.5 kg/s, the power output is: -290.75 kW -293.025 kW 289.025 kW ▶ 293.025 kW 288.475 kW
