Supercritical, uniform flow of water occurs in a 5.0 m wide, rectangular, horizontal channel. The depth of flow is 1.5 m and the flowrate is 45 cu.m/s. The flow encounters a 0.25 m rise in the channel bottom. What is the new normal depth? Is the flow after the rise subcritical, critical or supercritical? Assume frictionless flow
A 10-m wide rectangular channel is carrying a discharge of 400 m3/s at a flow depth of 3.0 m. Determine the flow depth downstream of a step of 0.3 m if the step is: (i) a rise, and (ii) a drop. Does the water surface rise or drop downstream of the step in each case?
1. A rectangular channel is given with a width of B = 8.20m and an uniform flow depth of y = 13.62 m. The flow velocity is given as V = 8 m/s. a. Calculate the scales for discharge, time and force for a model of the channel at the scale of 1:12. b. Calculate the prototype hydrodynamic force acting on a pile of a bridge located in the channel if the force in the model is measured as F...
please show all the steps thank you 2. Water flowing at the normal depth in a rectangular concrete channel that is 12 m wide encounters an obstruction, causing the water level to rise above the normal depth at the obstruction and for some distance upstream. The water discharge is 126 m3/s, and the channel bottom slope is 0.00086. If the depth of water just upstream from the obstruction (yo) is 4.55 m, find the distance upstream to the point where...
A rectangular channel (n = 0.020) is to be 3.0 m wide. If a discharge of 3.00 m3/s is to be passed with the channel having an efficient section, what longitudinal slope is to be provided?

Subcritical, uniform flow of water occurs in a rectangular, horizontal channel with a width of 5.0 m. The flow has a depth of 2.0 m and a flow rate of 5.0 cu.m/s. The flow encounters a 0.25 m rise in the channel bottom. What is the new normal depth? Is the flow above the rise subcritical, critical or supercritical? Assume frictionless flow
Water flows in a 100 ft wide rectangular channel at flow rate = 300 ft3/sec. Manning's n = 0.015 and the bottom slope = 0.002.
