Hydraulics and Fluid Mechanics in ME In a single casing, multistage pump running at constant speed, the capacity rating is to be slightly lowered. It can be done by Designing new impeller Some other alterations in the impeller Trimming the impeller size to the required size by machining Not possible Designing new impeller Some other alterations in the impeller Trimming the impeller size to the required size by machining Not possible 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 × bH2 × √(2gh) Q = Cd × bH₁ × √(2gh) Q = Cd × bH × √(2gh) Q = Cd × b (H2 - H1) × √(2gh) Q = Cd × bH2 × √(2gh) Q = Cd × bH₁ × √(2gh) Q = Cd × bH × √(2gh) ANSWER DOWNLOAD EXAMIANS APP
