(06 Marks) A rectangular notch of crest width 400 mm is used to measure flow of water in a rectangular channel 600 mm wide and 450 mm deep. If the water level in the channel is 225 mm above the weir crest, find the discharge in the channel. For the notch assume Ca : 0.63 and take velocity of appro..Actrl'ihto account.
