Maximum flow rate through pipes

Maximum flow rate through pipes

Maximum flow rate through pipes

(OP)
i need to find the maximum flow rate of steam at 200 psi through a:-
1) half inch pipe
2) 1 inch pipe
3) 1.5 inch pipe

The maximum velocity will suffice, since the flowrate can be obtained from the velocity.
i know there are books which give these values, but i cannot seem to find any.

RE: Maximum flow rate through pipes

curiousguy,

What maximum velocity are you speaking of?  A recommended maximum velocity for steam to prevent erosion from condensate?  Prevent noise?  Optimum pipeline size and life? Sonic velocity?

Sonic velocity of 100-200 psi steam is 1600-1700 ft/sec.

Good luck,
Latexman

RE: Maximum flow rate through pipes

According to the Leslie Controls "Engineering Data Reference Tables"
Saturated Steam   1-15 psig   Heating Mains    4000-6000FPM
Saturated Steam   50-up psig   Misc            6000-8000FPM
Saturated Steam   200-up psig  Turb&Boiler leads 10K-15K FPM

1/2" pipe: 6000 Feet/Min 200 PSIG steam: 270#/H
1" pipe: 6000 Feet/Min 200 PSIG steam: 840#/H
1 1/2" pipe: 6000 Feet/Min 200 PSIG steam: 2060#/H
