Question

Helium is to be compressed from 150 kPa and 360 K to 600 kPa and 500 K A heat loss of 15 kJ kg occurs during the compression process Neglecting kinetic energy changes determine the power input required for a mass flow rate of 60 kg min where the constant pressure specific heat of helium is Cp 5 1926 kJ kg K
