Hydraulics and Fluid Mechanics in ME The length AB of a pipe ABC in which the liquid is flowing has diameter (d1) and is suddenly enlarged to diameter (d2) at B which is constant for the length BC. The loss of head due to sudden enlargement is (v₁ - v₂)²/2g (v₁² - v₂²)/g (v₁² - v₂²)/2g (v₁ - v₂)²/g (v₁ - v₂)²/2g (v₁² - v₂²)/g (v₁² - v₂²)/2g (v₁ - v₂)²/g ANSWER DOWNLOAD EXAMIANS APP
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 × bH₁ × √(2gh) Q = Cd × bH × √(2gh) Q = Cd × bH2 × √(2gh) Q = Cd × b (H2 - H1) × √(2gh) Q = Cd × bH₁ × √(2gh) Q = Cd × bH × √(2gh) Q = Cd × bH2 × √(2gh) ANSWER DOWNLOAD EXAMIANS APP
