Velocity Pressure/Velocity Examples; Converting Velocity Pressure To Fpm - Calculated Industries Sheet Metal/HVAC Pro Calc User Manual

VELOCITY PRESSURE / VELOCITY EXAMPLES
The Velocity Pressure/Velocity function uses an entered value to
calculate these four values:
1. Velocity (FPM)
2. Velocity (Pressure)
3. Metric Velocity (MPS)
4. Metric Velocity Pressure Number entered is assumed to be
(kPA)
The first time you perform this function, the values are displayed in
the order identified above. Subsequent calculations begin with the
last displayed value.

Converting Velocity Pressure to FPM

After obtaining Velocity Pressures (VP) from taking a traverse, your
calculator easily converts to Feet per Minute (FPM).
For example, convert the following VPs to FPM:
0.049"
0.123"
0.027"
KEYSTROKE
1. Enter first VP and convert to FPM:

• 0 4 9 Ç 0*
2. Enter second VP and convert to FPM:
• 1 2 3 Ç 0
3. Enter third VP and convert to FPM:
• 0 2 7 Ç 0
*The VP FPM function begins with the last displayed value. If FPM is not displayed
with the first press of Ç 0, continue pressing 0 until FPM is displayed.
