1. Superheated steam @ 20 bar and a temperature of 350C is fed to a steam turbine, which has minor heat losses from the turbine system of 80kJ/sec. The effluent from the steam turbine is saturated steam at 1 bar. If the amount of power output desired from this steam turbine is 200 kWatts, then what is the mass flow rate (in units of kg/min). Enthalpy inlet steam = 3139 kJ/kg Enthalpy outlet stream=2675.4 kJ/kg Mass flow rate of steam required=_ H20bar, 350C=3139 H-→ 1 bar, 350C=2675.4 kg/minute
