A chemical engineer is proposing to pump a certain organic solution (with s.g. of 8.66) from the reboiler of one distilling column to another without cooling before the solution enters the pump. The organic solution from the reboiler is a 114°C and 1.1 atm. Suppose there is a friction loss in the line from the reboiler to the pump and is measured to be 7 kN/m² and at the pump's discharge is 35 kN/m²: a. How far above the pump should the liquid level in the reboiler be to provide a NPSH of 2.5 m? b. If pumping is to be done at a rate of 10,000 kg/h, calculate the required horsepower to drive the pump (with efficiency of 60%) if it will deliver the solution to a height of 10 m which is at atmospheric pressure. Fluid flows at 2 m/s in this case.
