Saturated steam at 1 atm and 100°C is continuously generated from liquid water at 1 atm and 25°C by thermal contact with hot air in a counterflow heat exchanger. The air flows steadily at 1 atm. Determine values for m.m.  (steam)/ n.n.  (air) for the following cases.

Consider that air enters the exchanger at 1000°C and exits at 35°C.

The value for ??  m. (steam)/?? n. (air) is

Saturated water vapor leaves a steam turbine at a flow rate of 1.47 kg/s and a pressure of 0.51 bar. The vapor is to be completely condensed to saturated liquid in a shell-and-tube heat exchanger that uses city water as the cold fluid. The water enters the thin-walled tubes at 17oC and is to leave at 57.6 oC. Assuming an overall heat transfer coefficient of 2000 W/m2K, determine the required heat exchanger surface area and the water flow rate. cp,c...

Two products enter an indirect contact heat exchanger that uses steam for heating. The first product which contains 15% solids enters at the rate of 3 kg/hr and at 10 °C. The second stream which contains 20% solids enters at the rate of 4 kg/hr and at 20 °C. Saturated steam at 140 °C enters the heat exchanger at 0.5 kg/hr with a quality of 95% and exits at 10% quality at 140 °C. The resulting mixture enters an indirect...

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).

An industrial facility needs a flow of 100 gpm of hot water at 180°F, 50 psia. Two designs are being considered to make the hot water. In Design 1, the hot water is produced by injecting steam into an insulated mixing chamber through which the water passes. The water enters the chamber at 50°F, 50 psia. Steam is injected into the chamber at 325°F, 50 psia. The hot water leaves at the required flow rate and temperature. For this system...
