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. 11 m 10 m 12 m 20 m 11 m 10 m 12 m 20 m ANSWER DOWNLOAD EXAMIANS APP

Fluid Mechanics The pressure drop per unit length of pipe incurred by a fluid 'X' flowing through pipe is Δp. If another fluid 'Y' having both the specific gravity & density just double of that of fluid 'X', flows through the same pipe at the same flow rate/average velocity, then the pressure drop in this case will be Δp² Δp 2Δp Δp/2 Δp² Δp 2Δp Δp/2 ANSWER DOWNLOAD EXAMIANS APP
