Pump/Pipe and open channel loop
Pump/Pipe and open channel loop
(OP)
I am working on an interactive display for an exhibit at a museum. I am creating a river flow channel. It consists of a re-circulating system with the pump and pipe system under the channel and a close to rectangular cross section for the river channel above.
I need to calculate the pressure drop for the system.
I am trying to size the pump and pipe system.
Any suggestions???
Details:
-10ft long, 2.666ft wide, and 0.5ft deep channel.
-PVC piping
-Required flow rate 0.22 ft/s in channel
-Must be a single phase powered pump

RE: Pump/Pipe and open channel loop
Using the Mannings equation, the slope calculates to just 0.00002 ft/ft.

You probably will have about 3-5 feet of headloss in your piping.
You need a low head pump; sized for 131 gpm @ 3-5 ft TDH.

So you pump should be sized for 131 gpm @ 13-15 ft TDH.
You can probably find a Crane Deming pump that will work in that flow range.
