Helium is to be compressed from 120 kPa and 310 K to 700 kPa and 430 K. A heat loss of 20 kJ/kg occurs during the compression process. Neglecting kinetic and potential energy changes, determine the power input required for a mass flow rate of 90 kg/min. (The constant pressure specific heat of helium is ?? = 5.1926 ??/??∙?.)
