It is proposed to pump 10,000 kg/h of toluene at 114°C 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 7 kN/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?

100% High pressure water and compressed air are delivered to some operating rooms. Bored one day, with no patients around, you take the cap off the nozzle to see what would happen. Water flows through the vertical pipe and nozzle and then exhausts into the air as shown in the diagram. The water pressure in the pipe at position 1 is 3 atm. The pressure when the water discharges to the air is 1 atm. Position 2 identifies the nozzle, 0.75 m above position 1, where the water flow has been constricted from an 8-cm diameter pipe to a 3-cm diameter nozzle. Assume that the free jet remains a stream of water with a 3-cm diameter. Assume no friction losses. Free jet -3 cm diameter 0.75 m a) Determine the mass flow rate of water through pipe at position 1 in kg/s. 3 atm 8 cm diameter b) Determine the height, h, the water jet can rise. c) Calculate the friction factor inside the 8-cm pipe and determine if the assumptions of negligible friction losses was reasonable.
