3 Pump Two reservoirs are connected by a pipeline that goes up and over a hill as shown. A pump is used to transfer water from the reservoir on the left to the reservoir on the right. Assume the lower reservoir has a water elevation of 300', the upper reservoir is at 600', and a 1' diameter, 3000' long cast iron pipe connects the two. The temperature is 60°F. (consider only the distributed head loss; ignore minor losses) a) What is the minimum required energy (in ft) that the pump needs to supply in order to transfer the water from the lower to upper reservoir at 10 cfs? b) If the pump supplied a maximum of 500 ft of head, what is the greatest allowable elevation (in ft) in the pipeline, assuming a 10 cfs flowrate? c) If the pump were taken offline while the pipeline was full of water, there is the potential for a siphon to form -- water from the upper reservoir could naturally flow to the lower reservoir. Estimate the flowrate Q in the siphon in cfs. (assume the water flows without any additional headloss from the offline pump or complications due to pipe elevation.)
