2. Air enters a steady-flow turbine at 1 MPa, 1200 K, and a mass flow rate of 0.2 kg/s. It exits the turbine at 0.2 MPa and 900 K. Changes in kinetic and potential energies are negligible. Heat is lost to the surrounding at the rate of 15 kW. Assume air is an ideal gas with constant specific heats: R = 0.287 kJ/kgK, cp = 1.005 kJ/kgK, cv = 0.718 kJ/kg.K a) What is the turbine's power output? > b) If the inlet to the turbine is a round pipe with a diameter of 10.5 cm, what is the inlet velocity?
