A four-stage compressor works between limits of 1 bar and 120 bar. The indexof compression in each stage is 1.25, the temperature at the start ofcompression in each stage is 30 ˚C, and the intermediate pressure areselected such that work is divided equally among the stages. If the clearanceis negligible: Calculate:1 the intermediate pressure in each stage2 the temperatures at the end of each stage3 the mass flow rate in kg/h if work input is a unit kW
