fire pump critical speed
fire pump critical speed
(OP)
hello all,
we have a 20" suction, 16" discharge 5400 gpm fire pump.
Is there any concept like "criticial speed" for suction and discharge lines.?
Does any code indicate a maximum speed not to exceed in these lines.
thanks..

There is no code limitation on velocity per say, although the higher velocity you have, the more pressure drop you will experience in the pipe, which leaves less pressure for your outlet flows. There are minimum pressure and minimum flow requirements at your outlets.

I guess these are recommended velocities.
what should be the maximum allowable velocity you think.
could we say 3.4 m/s for 20".
