Robert manning equation
WebManning’s Equation Example: • Given a V-shaped channel with a HGL slope of 0.001, a top width of 10 feet, and a depth of 5 feet, determine the velocity of flow using the Manning’s equation. Find the discharge in both ft 3/sec (cfs) and m /sec (cms). Manning’s Equation Substituting: R = (25 ft2)/14.14 ft R = 1.77 ft WebManning’s formula was proposed by Robert Manning (an Irish engineer) to calculate uniform flow in open channel. It is probably the most widely used uniform-flow formula around the world. Its extensive usage is due to the following reasons: (i) The majority of open channel flows lies in rough turbulent region;
