It is proposed to pump 5,000 kg/h of toluene at 325K and 1 atm 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 10 kN/m2, how far (in m, four decimal places) above the pump must the liquid level in the reboiler be maintained to give a net positive suction head of 11m?

Question

It is proposed to pump 5,000 kg/h of toluene at 325K and 1 atm 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 10 kN/m2, how far (in m, four decimal places) above the pump must the
liquid level in the reboiler be maintained to give a net positive suction head of 11m?
