A pump is used to raised water to a reservoir through 800 m. long of 20 cm diameter with Cw of Hazen-William’s Equation equal to 110. If the pipe is to be replaced with a new one having the same length but with a diameter of 25 cm and Cw = 130, determine the power save if the flow is to be maintained at 100 liters per second. Draw the approximate EGL and HGL.
