Question

Same as it is observed in the sink of a kitchen when water from the tap falls on it, the water in an open channel can change from high velocity regime (v1, hi) to a lower velocity and lower energy regime (v2, h2) as it is depicted in figure. Pressure in sections 1 and 2 is approximately the hydrostatic one and the friction on the wall can be considered as negligible. Using the continuity and momentum equations, obtain h2 and v as a function of hi and vi Sol, Ec. Masa (Mass Eq.): ρνǐhị = ρν2h2 Ec.
