Question

The approach velocity of flow over a weir is 0.5 m/s then what will be the value of additional head he in meter?

Answer 1

Answer:

The discharge in a channel with bottom width 3 m is 12 m3 s. –1. ... Substituting values in metre-second units: ... hence the approach- flow head is that for the normal depth (ℎ = 1.236 m):
