Steam enters a turbine at 5 kg/s with an enthalpy of 3000 kJ/kg and leaves with 2400 kJ/kg. Neglecting heat loss and changes in kinetic and potential energy, what is the power output?

  1. 600 kW
  2. 15,000 kW
  3. 3000 kW
  4. 12,000 kW

Answer

C. 3000 kW

Solution

W = m(h1 - h2) = 5(3000 - 2400) = 3000 kW.
