You are asked to specify a pump to deliver 800 bbl/day of 35° API distillate at 90 °F from a distillation column to a storage tank in a refinery. If the level in the tank is 20 ft above that in the column, the total equivalent length of pipe is 900 ft, and both the column and tank are at atmospheric pressure: (a) What horsepower would be needed if you use 1 ½ inch schedule 40 pipe? (b) What power would be needed if you use 1 in schedule 40 pipe? Assume the pipe is smooth-walled, express your answer in units of horsepower.
