Fluid Mechanics A centrifugal pump is used to pump water through a horizontal distance of 150 m, and then raised to an overhead tank 10 m above. The pipe is smooth with an I.D of 50 mm. What head (m of water) must the pump generate at its exit (E) to deliver water at a flow rate of 0.001 m³/s? The Fanning friction factor, f is 0.0062. 20 m 12 m 10 m 11 m 20 m 12 m 10 m 11 m ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics The energy loss in flow through ven-turimeter is less than that through flow nozzle, because in case of a flow nozzle, the Distance between the throat and the inlet is more Length is shorter Sudden expansion of flow in the downstream occurs Throat diameter is more Distance between the throat and the inlet is more Length is shorter Sudden expansion of flow in the downstream occurs Throat diameter is more ANSWER DOWNLOAD EXAMIANS APP
