Water at 20-degrees centigrade enters a 10-cm-diameter pipe at a flow rate of 0.1m3/s from a reservoir on the side of a hill. The pipe is made of plastic and considered smooth. The pipe which runs for 200 meters down the hill also contains eight 90-degree flanged smooth bends and a swing check valve before emptying into another reservoir. Your client wants a flow rate of 0.1m3/s into the second reservoir and wants to know how high up the second reservoir needs to be to maintain this flow rate. What is the minimum height needed for the hight reservoir in meters to three significant digits?

You need to pump water at 20 C from an open reservoir at flow rate of 1.4 x 10^-3 m3/s through a pipe with an inside diameter of 0.03m, using a centrifugal pump having an (NPSH)aq =2.5 m and the equivalent length on the suction side is 3m. There are several minor losses: four standar 90 flanged elbows, and fully open flanged globe valve, fully open flanged gate valve, and the Entrance. What is the the maximum distance above the...

Water is flowing through a 10-cm-diameter water pipe at a rate of 0.1 m/s. Then, a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water as it exits the diffuser to atmospheric pressure, as shown in the given figure. Disregarding frictional effects, determine the force exerted on the bolts due to the water flow. Take the density of water to be 1000 kg/m3 -t- d 10 cmm D = 20...
