Hydraulics and Fluid Mechanics in ME The length AB of a pipe ABC in which the liquid is flowing has diameter (d1) and is suddenly contracted to diameter (d2) at B which is constant for the length BC. The loss of head due to sudden contraction, assuming coefficient of contraction as 0.62, is v₂²/2g v₁²/2g 0.5 v₁²/2g 0.375 v₂²/2g v₂²/2g v₁²/2g 0.5 v₁²/2g 0.375 v₂²/2g 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
