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 = (3Cd × a)/√(2h) Q = (Cd × a)/√(2gh) Q = Cd × a × 2gh Q = (2/3). Cd × a × h Q = (3Cd × a)/√(2h) Q = (Cd × a)/√(2gh) Q = Cd × a × 2gh Q = (2/3). Cd × a × h ANSWER DOWNLOAD EXAMIANS APP
