ABSOLUTE CALCULATION, P4 = 0
¤
For flows that can be calculated by the equation:
q = 1/1000 x (b + mh) x v for h ≤ d
q = 1/1000 x ((b + md)d + (B(h - d))) x v for h ≥ d
m = (B - b)/d
where : q = flow rate, l/s d = height of transition, cm
B = channel top width, cm h = head, cm
b = channel base width, cm v = flow velocity, cm/sec
RATIOMETRIC CALCULATION, P4 = 1
