1.A rectangular concrete channel is 3 m wide and 2 m high. The water 20 deg Celsius in the main channel is 1.5 m deep and is flowing at a rate of 30 m^3/s. determine the flow area, wetted perimeter, and hydraulic radius. is the flow laminar or turbulent?
2. A trapezoidal channel is carrying water at a normal depth of 5.2 ft, the channel has a bottom width of 10 ft and side slopes of 2 H to 1 V. It is running on a slope of 0.005 ft/ft. What will be the shear stress in lb/ft^2 exerted on the channel bed by this flow.
