where: Q = discharge over in ft 3 /s . C e = effective discharge coefficient . h 1 = head on the in ft . h 1e = h 1 + k h = angle of V-notch. The head correction factor, k h, is a function of (figure 7-6a). However, for fully contracted traditional 90-degree V-notch s, equation 7-6 and the rating table discussed later produce comparable accuracy.
