A turbine operates under steady flow conditions, receiving steam at the following state: pressure 1200kPa, temperature 188℃, enthalpy 2785 KJ/kg, speed=33.3m/s and elevation of 3m . The steam leaves the turbine at the following state; pressure=20kPa, enthalpy 2512 kJ/kg. Speed 100m/s and elevation 0 m. Heat is lost to the surroundings at the rate of 0.29 kJ/s. If the rate of steam flow through a turbine is 0.42 kg/s, what is the power output of the turbine in kW?

A turbine operates under steady flow conditions, receiving steam at the following state: pressure 1200kPa, temperature 188℃, enthalpy 2785 KJ/kg, speed=33.3m/s and elevation of 3m . The steam leaves the turbine at the following state; pressure=20kPa, enthalpy 2512 kJ/kg. Speed 100m/s and elevation 0 m. Heat is lost to the surroundings at the rate of 0.29 kJ/s. If the rate of steam flow through a turbine is 0.42 kg/s, what is the power output of the turbine in kW?
3. A turbine operates under steady flow conditions, receiving steam at the following state: pressure 1200kPa,
temperature 188°C, enthalpy 2785 KJ/kg, speed=33.3m/s and elevation of 3m . The steam leaves the turbine
at the following state; pressure=20kPa, enthalpy 2512 kJ/kg. Speed 100m/s and elevation 0 m. Heat is lost to
the surroundings at the rate of 0.29 kJ/s. If the rate of steam flow through a turbine is 0.42 kg/s, what is the
power output of the turbine in kW?
