Find the specific compressor work and the exit temperature
Civil Engineering
1. A nozzle is required to produce a flow of air at 200 m/s at 20?C, 100 kPa. It is estimated that the nozzle has an isentropic efficiency of 92%. What nozzle inlet pressure and temperature are required, assuming the inlet kinetic energy is negligible?
2. A water-cooled air compressor takes air in at 20?C, 90 kPa and compresses it to 500 kPa. The isothermal efficiency is 88% and the actual compressor has the same heat transfer as the ideal one. Find the specific compressor work and the exit temperature.
