Steady state water enters y 220ºF into a heat exchanger, leaves it at y 320ºF. The steam that leaves the exchanger is fed to a turbine from which it comes out with a quality of 90% and 1 psia. The exchanger uses air that enters 360ºF and 1 atm with a volumetric flow of 3000 ft3 / min, and exits at 280ºF at the same pressure. Determine the power in the turbine (Btu / min).

Steam at 400 psia and 50 percent quality is heated in a steady-flow heat exchanger until it becomes saturated vapor. It is then expanded isentropically through a turbine to 1 psia. This is followed by cooling in a second heat exchanger and then isentropic compression to the initial condition. Determine the Carnot efficiency for the cycle and the net work output.

Water is used to cool R-134a in the condenser of a heat exchanger. The refrigerant enters the counter-flow heat exchanger at 800 kPa, 80 0C and a mass flow rate of 2 kg/s. The refrigerant exits as a saturated liquid. Cooling water enters the condenser at 500 kPa and 18 0C and leaves the condenser at 30 0C. Determine the necessary mass flow rate of water. Each fluid is assumed to flow at constant pressure.
