Nozzle is a device that can be used to O A. increase the mass flow rate O B. reduce the mass flow rate O C. increase the exit velocity O D. reduce the exit velocity

Q . It is proposed to pump 8,000 kg/h of toluene at 114 oC and 1.1 atm abs pressure from the reboilerof a distillation tower to a second distillation unit without cooling the toluene before it enters thepump. If the friction loss in the line between the reboiler and pump is 7 kN/m2 and the density oftoluene is 866 kg/m3 . How far above the pump must the liquid level in the reboiler be maintained togive a net positive suction head of 3.5 m? Calculate the power required to drive the pump if the pumpis to elevate the toluene 10 m. The pressure in the second unit is atmospheric and the friction loss inthe discharge line is 35 kN/m2 . The velocity in the pump discharge line is 4 m/s.

8. . Equation for Law of conservation of mass and energy for a nozzle is
