Compressed Air Flow Calculator

Flow Rate Formula:

\[ Q = A \times v \]

Flow Rate (m³/s):

1. What is a Compressed Air Flow Calculator?

Definition: This calculator determines the volumetric flow rate of compressed air based on the cross-sectional area of the pipe and the flow velocity.

Purpose: It helps engineers and technicians design and analyze compressed air systems for industrial applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q = A \times v \]

Where:

\( Q \) — Volumetric flow rate (cubic meters per second, m³/s)
\( A \) — Cross-sectional area of the pipe (square meters, m²)
\( v \) — Flow velocity (meters per second, m/s)

Explanation: The flow rate is calculated by multiplying the pipe's internal cross-sectional area by the velocity of the air flow.

3. Importance of Air Flow Calculation

Details: Proper flow rate calculation ensures efficient system design, prevents pressure drops, and helps select appropriately sized components.

4. Using the Calculator

Tips: Enter the pipe's internal cross-sectional area in m² and the air velocity in m/s. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find the cross-sectional area?
A: For circular pipes: \( A = \pi \times r^2 \) where r is the internal radius.

Q2: What's a typical compressed air velocity?
A: Recommended velocities are typically 6-9 m/s for main lines and 9-15 m/s for branch lines.

Q3: Does this account for pressure and temperature?
A: This calculates actual flow rate. For standard flow rate (at reference conditions), additional calculations are needed.

Q4: How do I convert to other units?
A: 1 m³/s = 60,000 L/min = 2118.88 CFM (cubic feet per minute).

Q5: What affects compressed air velocity?
A: Pressure, pipe diameter, system demand, and restrictions like valves and fittings.
