A Roots blower supplies air at the rate of 1 kg/s. The pressure ratio of the blower is 2:1 with an intake pressure and temperature of 1 bar and 70°C, respectively. Find the power required to drive the blower. Take R = 0.29 kJ/kg K. If a vane pump having the same air flow, pressure ratio and intake conditions has the volume reduced to 0.7 of the intake volume before delivering the air, estimate the power required.
