Air at a pressure of 400KPa and a temperature of 700 degree Celsius expands in a turbine at steady state to a pressure of 100KPa. The work output is 260KJ/Kg, and the heat transfer from the turbine is 30KJ/Kg. Assuming air is an ideal gas with a constant specific heat of1.0035KJ/Kg.K, and the temperature of the surroundings is 298.15K, determine;

  • the turbine exit pressure
  • the change of entropy of the air per unit mass of flow
  • the internal entropy production.
