Pressure to Velocity Conversion Charts
The AXD 550 MicroManometer converts pressure
readings to velocity using the formula for standard
conditions:
V
(fpm)
= 4005
P
∆
Pressure in inches H
2
0
V
(m/s)
= 1.29
P
∆
Pressure in Pa
Please note that for small pressure readings, an
increment in pressure can cause large steps in
velocity, but at larger readings, the steps in
velocity are much less pronounced as a percentage
of reading. A Micro-Manometer should not be
used with a pitot tube at very low differential
pressures to measure velocity, because resolution
errors will be large.
The following graphs show approximate velocities
for certain differential pressures in the range0–
0.10 inches H

0 (0–25 Pa).
