Hydraulics and Fluid Mechanics in ME The error in discharge (dQ/Q) to the error in measurement of head (dH/H) over a triangular notch is given by dQ/Q = 3/2 × (dH/H) dQ/Q = 3 × (dH/H) dQ/Q = 5/2 × (dH/H) dQ/Q = 2 × (dH/H) dQ/Q = 3/2 × (dH/H) dQ/Q = 3 × (dH/H) dQ/Q = 5/2 × (dH/H) dQ/Q = 2 × (dH/H) 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 × bH × √(2gh) Q = Cd × bH₁ × √(2gh) Q = Cd × bH2 × √(2gh) Q = Cd × b (H2 - H1) × √(2gh) Q = Cd × bH × √(2gh) Q = Cd × bH₁ × √(2gh) Q = Cd × bH2 × √(2gh) ANSWER DOWNLOAD EXAMIANS APP
