Energy systems components. Pumps. Straight cast iron pipe is used for water transportation from lake to a reservoir. The flow rate of water is 247 m3 h1 and the total length of the pipe is 396 m. Determine the minimum theoretical pump power in kW, required to transport water from the lake to the reservoir which is located 43 m above the lake, if the average head loss is 20 m per 100 meters of pipe length. Provide the answer to three significant figures and enter the numerical value only (e.g. 0.123, 123, 123000, 0.0123, but not 123 kW). Round your answer to 3 significant figures. Add your answer
