It is proposed to pump 10,000 kg/h of saturated toluene at 114oC and 1.1 atm a from the reboiler of a distillation tower to a second distillation unit without cooling. If the friction loss in the reboiler and pump is 7 kPa and density of toluene is 866 kg/m3, how much liquid level in the reboiler is to be maintained to give a net suction head of 2.5 m? Calculate the power required to drive the pump if the pump is to elevate the toluene to 10 m to a second unit at atmospheric pressure. Assume friction loss in the discharge line to be 35 kPa. Pump efficiency is 62%.
