I am trying to calculate the flow depth over a 36-inch pipe embedded in a concrete, rectangular channel for a given flow rate. Upstream of the pipe, the channel slopes from the top of the pipe away from the pipe. Downstream of the pipe, the channel starts at about the centerline of the pipe...
Flexible couplings are being used for this pump replacement project to provide some alignment flexibility because we are connecting some new piping at the pump to existing suction and discharge piping. The suction piping is 8" (and the discharge piping is 6"). There is a 90 degree elbow a few...
I need to calculate the force on a fitting upstream of a pump (on the suction side) to determine whether restraint is needed across a flexible coupling at the pump. The reservoir that the pump is taking water from is below the pump (suction lift condition). How do I calculate the forces on the...
Some engineers have indicated that for open channel flow applications at a certain steep pipe slope the Manning Equation is no longer applicable and another method must be used to determine the carrying capacity of the pipe. I'm looking for input on: (1) whether others agree with this concept...
Thank you CVG for responding to my thread. You appear to be indicating that the Manning Equation should be used for this application (unless I'm missing something). Because the channel slope is zero (flat), I would calculate a flow of zero using this equation (which is not the case). There is...
I am trying to calculate the water level in a flat rectangular channel that has a free discharge (i.e. no backwater effects, flow drops to a lower water surface level downstream of the channel) and a known flow rate. What is the appropriate equation to calculate flow depth?
Thanks.
