Need to move 1,400 gpm of water 3,500 ft, 6 ft. up hill and discharge. Have 7 ft. of head psi. What size pipe?
WATER WILL BE DISCHARGED INTO A RESERVOIR. I HAVE A 42" I.D. STAND PIPE @ START POINT THAT IS 14 FOOT TALL. SO WITH 6 FOOT OF ELEVATION CHANGE I HAVE 7 FOOT OF HEAD PRESSURE TO WORK WITH W/O OVERFLOWING THE STAND PIPE. I WANT TO USE PVC PIPE (80# PIP)
Answer:
I don't know how the first answerer came up with 2.6", it seems far too small. You might try the calculator (or equations) here:http://www.engineeringtoolbox.com/hazen-...
The calculator isn't set up to directly answer your question, but by a little trial and error I found that a 14" diameter seems to have head loss of approximately 7ft. Seems like a fairly big pipe, but 1400gpm is not a trivial flow
2.6"
does this involve math?? cuz i suck! hahaha lol
From the Cameron Hydrauliculic Data book, for a flow rate of 1400 GPM, and using steel pipe, the head loss per 100 feet of pipe for various sizes is as follows:
14" (13.25"ID) = 0.48 ft. per 100ft.
16" (15.25"ID) = 0.19 ft. per 100ft.
18" (17.18"ID) = 0.135ft. per 100ft.
How do you get a 1400 GPM flow into the standpipe??
6 inch
