OPEN CHANNEL FLOW: In a channel if the flow is steady (no changes in time)

h. h. S. B. OPEN CHANNEL FLOW: In a channel if the flow is steady (no changes in time) and uniform (no changes down stream) we have normal flow. Through a balance of the gravity (weight) to friction shear forces-for wide channels. or. where. Manning's Formula mks system.
