- can you please solve this for me, thanks. 10 kg/s of steam (H2O) enters a turbine at 10 m/s and a specific enthalpy of 3500 kJ/kg and leaves at an outlet 10m below the inlet with a specific enthalpy of 2500 kJ/kg and a velocity of 20 m/s. Assume steady-state steady-flow. If the heat lost from the turbine is 20% that of the turbine work, determine a.) the turbine horsepower. If the turbine is coupled to a generator with a 90% electrical efficiency, and the turbine horsepower has an 80% mechanical efficiency, b.) how much income will a power plant generate in one year if the electrical energy is sold at PhP 3.51 per kW-hr? (Hint: Mechanical efficiency = actual turbine work / ideal turbine work. Electrical efficiency of a generator = electrical output / actual turbine work.)A turbine is driven by a system that enters the turbine at the ff. conditions: 500 kg/h, 44 atm, 450 deg C, 60 m/s linear speed.
