An unknown aqueous liquid mixture with a density of 71.7922 Ibm/ft3 and a viscosity of 1.005cP is pumped from an open tank to an elevated open tank at the rate of 5.7L/s. Both tanks have a considerably large cross-sectional area. All the piping system is made of 4 -in. schedule 40 commercial steel. The pump efficiency is 70%. If the inlet pressure to the pump is 1.8 bar, calculate; a) The power of the pump in kW,[20p] b) The pressure at the exit of the pump. [15 p]
