Hydraulics and Fluid Mechanics in ME The resultant upward pressure of the fluid on an immersed body due to its tendency to uplift the sub-merged body is called buoyancy reaction metacentre upthrust buoyancy reaction metacentre upthrust ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME The discharge through a small rectangular orifice is given by (where Cd = Coefficient of discharge for the orifice, a = Cross-sectional area of the orifice, h = Height of the liquid above the centre of the orifice) Q = Cd × a × 2gh Q = (Cd × a)/√(2gh) Q = (3Cd × a)/√(2h) Q = (2/3). Cd × a × h Q = Cd × a × 2gh Q = (Cd × a)/√(2gh) Q = (3Cd × a)/√(2h) Q = (2/3). Cd × a × h ANSWER DOWNLOAD EXAMIANS APP
