Problem #1:
A large stationary gas turbine power plants delivers 100 MW of power output to a generator. The
minimum temperature of the cycle is 300 K and the maximum is 1600 K. The minimum pressure
of the cycle is 100 kPa, and the compressor pressure rati
Problem #1:
Air is steadily compressed by a 5 kW compressor from 100 kPa and 17 C to 600 kPa and 167 C
at a rate of 1.6 kg/min. During this process, some heat transfer takes place between the
compressor and the surrounding medium at 17 C. Determine the ra
Problem #1:
The following data are for a simple steam power plant as shown in the figure. State 6 has x6 =
0.92 and velocity of 200 m/s. The rate of steam flow is 25 kg/s, with 300 kW of power input to the
pump. Piping diameters are 200 mm from the steam

Vapor Compression Cycles
9.8-9.11
Introduction
Vapor-compression cycle is used to provide cooling in
refrigerators and air-conditioners, and heating in heat
pumps.
Heating and cooling technologies based on the vaporcompression cycle have beco
