A centrifugal compressor used in a gas turbine engine increases the pressure of 2000 lbm/min of air from 15 psia to 150 psia. The enthalpy of the entering air is 150 BTU/lbm and of the compressed air is 300 Btu/lbm and 1.53 Btu/lbm of heat is lost ot the environment. Assuming no change in the kinetic or potential energy of the air, determine how much power is required to drive the compressor(hp).
