Hydraulics and Fluid Mechanics in ME The discharge through a wholly drowned orifice is given by (where H1 = Height of water (on the upstream side) above the top of the orifice, H2 = Height of water (on the downstream side) above the bottom of the orifice, and H = Difference between two water levels on either side of the orifice) Q = Cd × b (H2 - H1) × √(2gh) Q = Cd × bH2 × √(2gh) Q = Cd × bH × √(2gh) Q = Cd × bH₁ × √(2gh) Q = Cd × b (H2 - H1) × √(2gh) Q = Cd × bH2 × √(2gh) Q = Cd × bH × √(2gh) Q = Cd × bH₁ × √(2gh) ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME The depth of centre of pressure (h) for a vertically immersed surface from the liquid surface is given by (where IG = Moment of inertia of the immersed surface about horizontal axis through its centre of gravity, A = Area of immersed surface, and x = Depth of centre of gravity of the immersed surface from the liquid surface) (IG/Ax̅) - x̅ (IG/Ax̅) + x̅ (Ax̅/IG) + x̅ (IG/x̅) - Ax̅ (IG/Ax̅) - x̅ (IG/Ax̅) + x̅ (Ax̅/IG) + x̅ (IG/x̅) - Ax̅ ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME The force exerted by a jet of water (in a direction normal to flow) impinging on a fixed plate inclined at an angle θ with the jet is (waV²/g) × sin θ (waV/g) × sin θ (waV²/2g) × sin 2θ (waV/2g) × sin θ (waV²/g) × sin θ (waV/g) × sin θ (waV²/2g) × sin 2θ (waV/2g) × sin θ ANSWER DOWNLOAD EXAMIANS APP
