Hydraulics and Fluid Mechanics in ME Coefficient of velocity is defined as the ratio of Actual velocity of jet at vena contracta to the theoretical velocity None of these Actual discharge through an orifice to the theoretical discharge Area of jet at vena contracta to the area of orifice Actual velocity of jet at vena contracta to the theoretical velocity None of these Actual discharge through an orifice to the theoretical discharge Area of jet at vena contracta to the area of orifice 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 = (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
