Hydraulics and Fluid Mechanics in ME The Bernoulli's equation is based on the assumption that The velocity of flow is uniform across any cross-section of the pipe There is no loss of energy of the liquid flowing No force except gravity acts on the fluid All of these The velocity of flow is uniform across any cross-section of the pipe There is no loss of energy of the liquid flowing No force except gravity acts on the fluid All of these 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 × 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) Q = Cd × b (H2 - H1) × √(2gh) ANSWER DOWNLOAD EXAMIANS APP
