Hydraulics and Fluid Mechanics in ME The error in discharge (dQ/Q) to the error in measurement of head (dH/H) over a rectangular notch is given by dQ/Q = (dH/H) dQ/Q = (3/4) × (dH/H) dQ/Q = (1/2) × (dH/H) dQ/Q = (3/2) × (dH/H) dQ/Q = (dH/H) dQ/Q = (3/4) × (dH/H) dQ/Q = (1/2) × (dH/H) dQ/Q = (3/2) × (dH/H) ANSWER DOWNLOAD EXAMIANS APP
