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 = 5/2 × (dH/H) dQ/Q = 3/2 × (dH/H) dQ/Q = 3 × (dH/H) dQ/Q = 2 × (dH/H) dQ/Q = 5/2 × (dH/H) dQ/Q = 3/2 × (dH/H) dQ/Q = 3 × (dH/H) dQ/Q = 2 × (dH/H) ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME The Newton's law of resistance is based on the assumption that the Space around the body is completely filled with the fluid Planes of the body are completely smooth Fluid particles do not exert any influence on one another All of these Space around the body is completely filled with the fluid Planes of the body are completely smooth Fluid particles do not exert any influence on one another All of these 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
