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

Fluid Mechanics A bed of spherical particles (specific gravity 2.5) of uniform size 1500 μm is 0.5 m in diameter and 0.5 m high. In packed bed state, the porosity may be taken as 0.4. Ergun's equation for the above fluid-particle system (in SI units) is given below : Δ P/L = 375 x 10³ VOM + 10.94 x 10⁶ V²OM (SI units) If water is to be used as the fluidising medium, the minimum fluidisation velocity, VOM is 12 mm/s 24 mm/s 16 mm/s 28 mm/s 12 mm/s 24 mm/s 16 mm/s 28 mm/s ANSWER DOWNLOAD EXAMIANS APP
