A long- throated flume is built in a rectangular 1 m widechannel having a throat width of 0.5 m. The upstreamhead is 0.6 m.Assume a Cd of 1.0. Headloss = 0.05 m. a) calculate the discharge through the flume. b) for the flow computed in part (a), calculate the throatwidth required to cause a choke. c) assess if the 0.5 m throat width causes a critical,subcritical, or supercritical flow.
