Fluid processes and fluid mechanics

Rotary air compressor problem 1a/ a rotary air compressor increases the absolute pressure of the air from 100 kNm-2 to 230 kNmm-2 and the specific volume of the air is reduced from 0.7m3 kg-1 to 0.46 m3 kg-1. If the internal energy of the air is increased by 40 kj kg-1 find the change in enthalpy of 8 kg of air. b/ If at ...continues
