This calc is mainly for pipes full with water at ambient temperature and under turbulent flow. If you know the slope rather than the pipe length and drop, then enter '1' in 'Length' and enter the slope in 'Drop'. If the cunduit is not a full circular pipe, but you know the hydraulic radius, then enter (Rh×4) in 'Diameter'.

Calculate fluid flow and pipe velocities in pipes and tubes
Imperial units
Fluid flow velocity in a circular pipe can be calculated with Imperial or American units as
v = 1.273 q / d2 Snapshot pro 3 4 0 8.
= 0.4084 qgpm / din2 (1)
where
v = velocity (ft/min, ft/s)
q = volume flow (ft3/s, ft3/min) Colorsnapper 2 1 3 2 download free.
d = pipe inside diameter (ft)
qgpm = volume flow (US gal/min, gpm)
din = pipe inside diameter (inches)

SI units
Fluid flow velocity in a circular pipe can be calculated with SI units as
v = 1.273 q / d2 (2)
where
v = velocity (m/s)
q = volume flow (m3/s)
d = pipe inside diameter (m)

Example - Flow Velocity in a Steel Pipe
60 US gal/min is flowing through a 4 inch schedule 80 steel pipe. The internal diameter of the pipe is 3.83 in. The velocity can be calculated as
v = 0.4085 (60 gal/min) / (3.83 in)2
= 1.7 ft/s
