Hydraulics and Fluid Mechanics in ME In a forced vortex motion, the velocity of flow is directly proportional to its radial distance from axis of rotation inversely proportional to the square of its radial distance from the axis of rotation inversely proportional to its radial distance from the axis of rotation directly proportional to the square of its radial distance from the axis of rotation directly proportional to its radial distance from axis of rotation inversely proportional to the square of its radial distance from the axis of rotation inversely proportional to its radial distance from the axis of rotation directly proportional to the square of its radial distance from the axis of rotation 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 = (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 ANSWER DOWNLOAD EXAMIANS APP
