Critical depth channel
WebCritical Depth and Critical Slope for a Rectangular Channel Solving for yc and substituting q = Q/b, leads to the following equation for the critical depth in a rectangular channel: yc = (q2**/g)**1/3. Thus, the only parameters needed to calculate the critical depth are the flow rate and the rectangular channel width. Weblook at every possible instance of critical depth problems. What is critical depth? In open channel hydraulics, critical depth is the depth of flow (for a given discharge) where the …

Example #4: Find the critical slope for a rectangular channel with bottom width of 3 ft, Manning roughness of 0.011, carrying a flow rate of 15 cfs. Solution: First calculate the critical depth from: y c = (q 2/g)1/3 Substituting values: y c = ((15/3) 2/32.2)1/3 = 0.9191 ft A c = by c = (3)(0.9191) = 2.757 ...
WebApr 1, 2012 · The flow depth corresponding to the minimum specific energy for a given discharge in an open channel is known as the critical depth. The governing equation for critical depth computation is [1] (1) Q 2 g = A 3 B , where Q is the discharge given to compute the corresponding critical depth, g is the gravitational acceleration, A is the … WebNote: for non prismatic channel, the channel section varies along the length of the channel and hence, the specific energy differs from section to section. Case.2 When Discharge is Variable. ⇒ In the above section the critical-flow condition was derived by keeping the discharge constant. (If y = constant, and discharge is increase then specific energy is …
