Chapter 1, Problem 1.12P

Air enters a heat exchanger at a rate of 5000 cubic feet per minute at a temperature of 50 F and pressure of 14.7 psia. The air is heated by hot water flowing in the same exchanger at a rate of 11,200 pounds per hour with a decrease in temperature of 10 F. At what temperature does the air leave the heat exchanger?

Steam enters a turbine with an enthalpy of 3300 KJ/kg and leaves with an enthalpy of 2400 kJ/kg. The power output of the steam turbine is 6 MW Determine the change in enthalpy per unit mass.  Determine the change in kinetic energy per unit mass.  Determine the change in potential energy, Determine the work done per unit mass of the steam flowing through the turbine. Calculate the mass flow Rate of the steam.
Air enters a gas turbine steadily at pressure 20 kPa, volumetric flowrate 1,000 m3/s, and temperature 300 oC. If the air exits the turbine at pressure 7 kPa and temperature 80 oC, determine the power generation in the turbine assuming changes in the kinetic energy and potential energy at the inlet and outlet condition is negligible. Determine the volumetric flowrate of air out of the turbine.
