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 For turbulent fluid flow in pipe, the expression for Prandtl one seventh power law is (where, r = pipe radius, x = distance). V/Vmax = (x.r)1/7 None of these V/Vmax = (r/x)1/7 V/Vmax = (x/r)1/7 V/Vmax = (x.r)1/7 None of these V/Vmax = (r/x)1/7 V/Vmax = (x/r)1/7 ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics Water hammer is caused, when water flowing in a pipe is suddenly brought to rest by closing the valve.
