Determine the final pressure using approximate analysis
Air is compressed isentropically from an initial state of 300 K and 101 kPa to a final temperature of 1000 K. Determine the final pressure using a) approximate analysis (using properties at the average temperature) and b) exact analysis.

If the minimum power into the compressor is 3 kW and it has an isentropic efficiency of 70% what is the output temperature? Use exact analysis.
A heat pump is used to heat a house.When the outside air temperaure is 10 F and the inside is maintained at 70 F, the heat loss form the house is 60000 Btu/hr. Determine the minimum electric power (kw) required to operate the heat pump.
Assuming that the compression process is isentropic and the mass flow rate is 0.15 kg/s determine the amount of power saved versus the use of a single compressor. Assume constant properties at 300 K.
