A steam turbine receives superheated steam at 1.4 MPa and 400°C (h = 3258 KJ/kg). The steam expands in the turbineisentropically to a pressure of 100 KPa (h = 2656.8 KJ/kg). The steam enters the turbine at 15 m/sec and exits at 60 m/sec. Theelevation difference between entry and exit ports is 3 m. Calculate the power output if the mass flow through the turbine is 0.5kg/sec. (Note: For isentropic process Q = 0) TSteamTurbinem
