1) Water is heated by steam in a heat exchanger. The water comes in at .4 MPa and 10°C and leaves at 110°C. flow rate of the water is 2 kg/s. 0.5 kg of steam comes in at a pressure of 0.6 MPa at 300°C, determine the exit temperature and state of the steam and rate of condensation if any

Homework Answers

Answer #1

In heat exchanger it is assumed that both side fluids don't mix. Also the pressure of fluid at inlet does not change. Like here the pressure of steam is 0.6 MPa throughout and of compressed water is 0.4 MPa. Properties are calculated based on these assumptions.

Steam at outlet is wet steam with 65.2% saturated water and remaining saturated steam at 158.83 ℃.

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).

The condenser of a large steam power plant is a heat exchanger in which steam is condensed to liquid water. Assume the condenser to be a parallel flow shell-and-tube heat exchanger consisting of a single shell and 10,000 tubes, each executing two passes. The tubes are of thin wall construction with D = 30 mm and the steam condenses on their outer surface. The heat transfer rate that must be effected by the exchanger is Q = 2 × 10^9...
