It is proposed to pump 10,000kg/h of toluene at 114C and 1.1atm abs pressure from the reboiler of a distillation tower to a second distillation unit without cooling the toluene before it enters the pump. If the friction loss in the line between the reboiler and pump is 7kN/m2 and the density of toluene is 866 kg/m3 1) How far above the pump must the liquid level in the reboiler be maintained to give a net positive suction head of 2.5m ? 2) Calculate the power required to drive the pump (60\% efficiency) if the pump is to elevate the toluene 10m, the pressure in the second unit is atmospheric, and the friction loss in the discharge line is 35kN/m2. The velocity in the pump discharge line is 2m/s
