Irrigation in the Pacific Northwest

Pipe Water Velocity and Minimum Pipe Diameter

Use the water velocity form to calculate the velocity of water in a pipe. Use the second form to calculate the diameter of a pipe required for 5 fps pipe velocity.

Water Velocity

Flow Rate:

gpm cfs acre-in/day acre-ft/day lps cms

Pipe Inside Diameter:

ft in mm cm m

Water Velocity:

fps

 

Minimum Pipe Diameter (5 fps)

Flow Rate:

gpm cfs acre-in/day acre-ft/day lps cms

Minimum Pipe Diameter:

ft in mm cm m
