Cooling water for a chemical plant must be pumped from a river 2,500 ft from the plant site. A preliminary design calls for a flow rate of 600 gpm and a 6" steel pipe. Calculate the pressure drop and the annual pumping costs if power costs 3 cents per kilowatt hour. Would the use of an 8" steel pipe reduce the power cost enough to offset the increased pipe cost? Assume $15/ft for the installed cost of 6" pipe and $20/ft for the installed cost of 8" pipe. Annual charges are estimated at 20% of the installed cost.

Transcribed Image Text:Cooling water for a chemical plant must be
pumped from a river 2,500 ft from the plant
site. A preliminary design calls for a flow rate
of 600 gpm and a 6" steel pipe. Calculate the
pressure drop and the annual pumping costs
if power costs 3 cents per kilowatt hour.
Would the use of an 8" steel pipe reduce the
power cost enough to offset the increased
pipe cost? Assume $15/ft for the installed cost
of 6" pipe and $20/ft for the installed cost of 8"
pipe. Annual charges are estimated at 20% of
the installed cost.
