A rectangular channel carries a discharge of 2.00 m3/sec per meter of channel width over a weir crest that is 1.4 m in height. The energy grade line upstream of the weir measure 2.7 m above the channel bottom. Determine the true coefficient of discharge in the weir equation, considering the energy losses. Also determine the amount of the energy losses in meters.
