Hydraulics and Fluid Mechanics in ME If a pump is handling water and is discharging a certain flow Q at a constant total dynamic head requiring a definite B.H.P., the same pump when handling a liquid of specific gravity 0.75 and viscosity nearly same as of water , the horse power required will be 0.75 B.H.P 1.5 B.H.P H.P./0.75 Same 0.75 B.H.P 1.5 B.H.P H.P./0.75 Same ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME The discharge through a small rectangular orifice is given by (where Cd = Coefficient of discharge for the orifice, a = Cross-sectional area of the orifice, h = Height of the liquid above the centre of the orifice) Q = (2/3). Cd × a × h Q = (Cd × a)/√(2gh) Q = (3Cd × a)/√(2h) Q = Cd × a × 2gh Q = (2/3). Cd × a × h Q = (Cd × a)/√(2gh) Q = (3Cd × a)/√(2h) Q = Cd × a × 2gh ANSWER DOWNLOAD EXAMIANS APP
