Compressed Air Flow Formula:
| From: | To: |
The compressed air flow formula Q = A × v calculates the volumetric flow rate in compressed air systems, where Q represents flow rate, A is cross-sectional area, and v is velocity of the air flow.
The calculator uses the fundamental flow rate equation:
Where:
Explanation: This formula calculates the volume of air passing through a given cross-section per unit time, essential for designing and analyzing compressed air systems.
Details: Accurate flow rate calculation is crucial for proper sizing of compressed air systems, determining pipe diameters, selecting appropriate compressors, and ensuring efficient system operation in industrial applications.
Tips: Enter cross-sectional area in square meters (m²) and velocity in meters per second (m/s). Both values must be positive numbers greater than zero for accurate calculation.
Q1: What units should I use for area and velocity?
A: Use square meters (m²) for area and meters per second (m/s) for velocity to get flow rate in cubic meters per second (m³/s).
Q2: How do I measure cross-sectional area for pipes?
A: For circular pipes, use A = π × (diameter/2)². For rectangular ducts, use A = width × height.
Q3: What is typical air velocity in compressed air systems?
A: Typical velocities range from 6-20 m/s, with lower velocities for larger pipes and higher for smaller pipes to minimize pressure drop.
Q4: Can this formula be used for other fluids?
A: Yes, this fundamental formula applies to any incompressible fluid flow, though additional factors may be needed for compressible fluids like air at high pressures.
Q5: How does temperature affect the calculation?
A: Temperature affects air density but not the volumetric flow rate calculation. For mass flow rate, density considerations become important.
