The minor losses for the system prior to the pump are given by KL = 12.0. The system curves for this pump are attached. If the flowrate is reduced to 1.4 m3/hr, and the upstream head requirement were 17 m, what would the electrical power requirement of the pump be?The system consists of 1200 m of 5 cm cast iron pipe, two 45° and four 90° flanged long-radius elbows, a fully open flanged globe valve, and a sharp exit into a reservoir. If the elevation at point 1 is 400 m, what gage pressure is required at point 1 to deliver 0.005 m3/s of water into the reservoir?

- Water 60°F flows at 10 ft/s in a 3 in. diameter pipe that is 100 ft long. There are six elbows (KL = 1) and two gate valves (KL = 0.3). The end of the pipe is at elevation 20 ft above the inlet. The pressure at the inlet is 50 psia. The roughness height is 0.0002 ft. Determine the head at the inlet, head loss,pressure drop due to losses, and absolute pressure at the end. *Show your correct and complete solution. Please include schematic diagram and assumptions.*For the flow configuration shown, you are required to design a pump station to transfer water from the bottom tank to the upper tank. In your own words, explain the steps that are needed to be followed for the design of the pump system. Your answer should be typed and not more than one page. The pipe equivalent roughness is 1.5 mm. And a valve with a k=10 is located just upstream of the lower reservoir (other losses are negligible). Take p=1000 kg/m”, g = 9.81 m/s?, and u = 1.179 x 102 kg/m.s.As seen in Figure 3 below, the water from the tank 1 is pumped to the tank 2 with a flow rate of 5,664 liters/s, passing through a pipe with a diameter of 50.8 mm and a length of 121.92 m. Some of the local losses in the system are also shown on the figure.
