A trapezoidal open-channel has a bottom width of 30 ft and side slopes of 2:1 (H:V). The channel is paved with a concrete surface. If the channel is laid on a slope of 0.0001 and carries a uniform flow at a depth of 6 ft, determine: a) the discharge (flowrate) in ft3/s. b) the state of the flow (critical, subcritical, super critical)?
