A radial type Boeing 747 blower is designed to deliver 1.3 m3/sec of air at a pressure of 107 KPa when operating at an altitude of 4000 m where the temperature is -10 °C and the pressure is 60 KPa It rotates at 18 000 RPM and is to have an adiabatic efficiency of 72%. It is to be tested at sea leve (P: 101 KPa and t=21 C) at a speed of 14 000 RPM. Assuming that the efficiency at the design point does not change, determine for the design under test conditions the power required to drive it in KW (61KW)
