A fluid modelling laboratory is required to analyse flow over a triangular sharp crested weir. Water from a rectangular tank is to be drained over a sharp crested weir that has a total angle of 60° i.e. 0 = 30° and a coefficient of discharge of 0.6. The plan area of the tank is 20m by 6m and the water surface is initially 0.8m above the crest. Show that the discharge equation for a triangular sharp crested weir is QA 8 15 Catane (29) ¹/2H ³/2 Calculate the time required to reduce the head above the weir crest from 0.8m to 0.2m
