pipe velocities
pipe velocities
(OP)
I am busy with fire pump design
what velocities do you recomend for:
-suction pipe (1.5m/s)
-suction manifold(1.5m/s)
-discharge piping (2m/s)
-discharge manifold(2m/s)?

RE: pipe velocities
The bigger the pipe- the faster the average velocity you can tolerate. The limitations on flow through a pipe are generally erosion and pressure loss- as you go up in pipe diameter you have a larger "core" of faster moving material and lower wall velocities.
I'd suggest trying some programs to calculate pressure loss over a conceptual piping run. Play with the pipe size and velocity until you get a feel for what flow is acceptable at different pipe sizes. Remember to include fittings in the piping run.
But as a start anyway- I'd suggest you could run your discharge velocities up to 2.5-3.0m/s with no real problems- as long as it's 200NB or larger
Cheers.
