Air Watts to Pascal Calculator

How to Use This Calculator

1. Enter the power in Air Watts (W) - this represents the power output of your air system.
2. Enter the volume flow rate in cubic meters per second (m³/s) - this is the amount of air moving per second.
3. Enter the air density in kg/m³. The default value is 1.225 kg/m³, which is the standard air density at sea level. You can adjust this for different altitudes or conditions.
4. Click the "Calculate" button to compute the pressure in Pascal.

Understanding the Formula

This calculator uses the formula: P = W / (ρ × Q), where:

• P = Pressure in Pascal (Pa)
• W = Power in Air Watts (W)
• ρ = Air Density in kg/m³
• Q = Volume Flow Rate in m³/s

This formula shows that pressure is directly proportional to power and inversely proportional to both air density and volume flow rate. This means that for a given power output, increasing the flow rate will decrease the pressure, and vice versa.

Practical Applications

This calculator is useful in HVAC engineering, compressed air systems, and other applications where you need to understand the relationship between power input and pressure output in air systems.

For example, if you know your air compressor produces 1000 Air Watts with a volume flow rate of 0.5 m³/s at sea level, you can calculate that it produces approximately 1640.71 Pascal of pressure (1000 W / (1.225 kg/m³ × 0.5 m³/s) = 1640.71 Pa).
