If two identical pumps with the characteristics tabulated in Problem are operating in parallel in that system, what will be the operating point of the pumps?
Problem
A centrifugal pump with the following characteristics is installed in a system to raise water from one reservoir to another. The water surface elevation in the first reservoir is 500 ft and in the second reservoir is 650 ft above mean sea level. The pipeline connecting the reservoirs includes 2 mi of 10-in.-diameter pipe. Determine the operating point of the pump in this system.
