Fluid Mechanics A 2" gate valve fitted in a pipe is replaced by a similar globe valve. Pressure drop in gate valve was Δp. For the same discharge, the pressure drop across globe valve is Δp Δp² < Δp > Δp Δp Δp² < Δp > Δp ANSWER DOWNLOAD EXAMIANS APP
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 11 m 10 m 20 m 12 m 11 m 10 m ANSWER DOWNLOAD EXAMIANS APP
