Hydraulics and Fluid Mechanics in ME In order to increase sensitivity of U-tube manometer, one leg is usually inclined by angle 'θ'. Sensitivity of inclined tube to sensitivity of U-tube is equal to 1/Cosθ Sinθ 1/Sinθ Cos θ 1/Cosθ Sinθ 1/Sinθ Cos θ 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 = (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 Q = (3Cd × a)/√(2h) Q = Cd × a × 2gh ANSWER DOWNLOAD EXAMIANS APP
