Converting FPM to Velocity Pressure
Calculate the Velocity Pressure (Imperial and Metric) if the FPM is
500:
KEYSTROKE DISPLAY
1. Enter 500 FPM to calculate Velocity:
o o 0.
5 0 0 Ç 0 FPM 89554.52
2. Calculate Velocity Pressure (VP):
0* VP 0.015586
3. Calculate Metric Velocity (MPS):
0 MPS 29.06888
4. Calculate Metric Velocity Pressure (KPA):
0 KPA 147928.99
5. Re-display entered value:
0 500.
*The VP ß © FPM function begins with the last displayed value. If FPM is not dis-
played with the first press of Ç 0, continue pressing 0 until FPM is displayed.
Note: The entered value is used to calculate all four values; for calculation of Velocity
(FPM), the entered value is assumed to be VP, and for calculation of VP, the entered
value is assumed to be FPM. For calculation of MPS, the entry is assumed to be kPA,
and for calculation of kPA, the entry is assumed to be MPS.
