1. It is proposed to pump 10,000 kg/h of toluene at 1140C and 1.1 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 7KN/m2 and the density of toluene is 866 Kg/m3. 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. Explain Pitot tube in detail. What is the difference between pitot tube and pitot static tube?
