Critical depth circular channel calculator
WebHow is critical depth calculated in open channel flow? VT gA = • F, = 1 Thus, when the specific energy is minimum for a given discharge flow will be critical flow and depth of flow will be called as critical depth of flow (y) and velocity of flow will be called as critical velocity. What is critical depth of Canal? WebThe ratio of Hydraulic radius and Hydraulic depth is 1/2 and the top width of the channel is 6m, calculate the hydraulic depth of the channel.
