A reboiler at the bottom of a distillation column contains an organic liquid at 1 atm and 3208F, at which its density is 0.7 g/cm3 , its viscosity is 0.5 cP, and its vapor pressure is 800 mmHg. The liquid must be pumped to another column at a rate of 200 gpm and discharges at 1 atm at a point 30 ft higher than the reboiler. You must select the best pump from those represented by the curves in Appendix H and determine where the pump is to be installed. The suction line of the pump will include 20 ft of 21 2 in. sch 40 pipe, eight elbows, four gate valves, and a contraction from the reboiler. Using the curves in Appendix H, determine:

(a) The required pump head, and the best pump for this job.

(b) The best size of impeller to use in this pump, the motor speed, and the motor horsepower.

(c) The efficiency and NPSH required for the pump.

(d) How far above the reboiler the pump can be installed and still function properly.
