Water flows in a new 20-cm-diameter, 300-m-Jong ductile iron pipe between reservoirs A and B, a~ shown in Figure P4.2.l. The pipe is elevated at S, which is 150 m downstream from reservoir A. The water surface difference between the two reservoirs is 25 m. Determine the head that should be provided by a booster pump I 00 m downstream from reservoir A if D..s is 3 m and the pressure head at that location must be kept above -6 m because of cavitation concerns. Sketch the EGL and the HGL for the pipeline .
