A rotary blower moves gas volumetrically, but real delivery depends on speed, displacement, pressure and leakage. This calculator treats flow as an entered constant and performs time and unit conversions.
Wedding Rotary Blower Interactive Calculator
Enter a constant volumetric flow and run time. Outputs are ideal conversions—not a Wedding blower performance prediction.
Equation Used
- Entered volumetric flow remains constant for the full run time.
- Unit conversions use the displayed fixed factors.
- Accumulated volume is ideal arithmetic.
- Both values describe compatible volumetric conditions.
- Pressure, temperature, leakage, slip, power, efficiency, sound and mechanical limits are omitted.
Blower-System Context
The U.S. Department of Energy fan-systems program treats fan and blower performance as a system assessment problem. This page does not calculate a machine curve; it converts an entered flow.
What This Calculator Represents
Compare flow units and accumulated volume for the constant flow and duration you enter.
Flow and Volume
CFM=35.3147Q
L/s=1000Q/60
ft3=35.3147m3
Worked Example
At 1.13 m3/min for 24 hours, ideal accumulated volume is 1,627.2 m3; flow is about 39.9 CFM or 18.8 L/s.
Assumptions and Limits
- Calculated: constant-flow conversions and accumulation.
- Illustrated: a schematic two-rotor blower.
- Not calculated: displacement, pressure, leakage, power, efficiency or operating curve.
