A pump draws water from reservoir A and lifts it to reservoir B as shown in the figure. The loss of head from A to 1 is four times the velocity head in the 50mm pipe and loss of head from 2 to B is 15 times the velocity head in the 100mm pipe. The pump discharge rate us 50 liters per second. Determine the following: A. Power delivered by the pump in KW B. Pressure head at pt. 1 in meter C. Pressure head at pt 2 in meter
An incompressible fluid is flowing at a steady rate in a horizontal pipe. From a section, the pipe divides into two horizontal parallel pipes of diameters di and d2 (where d₁ = 4d₂) that run for a distance of L each and then again join back to a pipe of the original size. For both the parallel pipes, assume the head loss due to friction only and the Darcy-Weisbach friction factor to be the same. The velocity ratio between the bigger and the smaller branched pipes is
