Pressure to Velocity Calculator

How do you convert pressure into velocity? Following will help you find velocity from dynamic pressure and fluid density. Enter the dynamic pressure and fluid density to find the velocity.

Enter the Dynamic Pressure in Pascals or PSI. Enter the Fluid Density in kg/m³ or lb/ft³. The calculated Velocity will be displayed here.

Enter the Total Pressure in Pascals or PSI. Enter the Temperature in Kelvin (K). Enter the Volume Flow Rate in m³/s or ft³/s. The calculated Velocity will be displayed here.

What is Pressure to Velocity?

Pressure to Velocity conversion is used in fluid dynamics. It helps determine the speed of a fluid based on its pressure and density.

Tool Using Guide

Enter Dynamic Pressure: Input the pressure value in Pascals or PSI. For example, 1000 Pascals.
Enter Fluid Density: Input the density value in kg/m³ or lb/ft³. For example, 1.225 kg/m³.
Calculate Velocity: Click “Calculate” to get the velocity.

Formula

The formula to calculate velocity is:

V = \sqrt{\frac{2 \times q}{p}}

Variables

Variable	Description
V	Velocity (m/s)
q	Dynamic Pressure (Pa)
p	Fluid Density (kg/m³)

How To Convert Pressure to Velocity

Example 1

Input:

More Calculators

Dynamic Pressure = 1000 Pa,
Fluid Density = 1.225 kg/m³

Calculation:

1. Use the formula:

V = \sqrt{\frac{2 \times 1000}{1.225}}

2. Calculate

\frac{2000}{1.225} = 1632.65

3. Find the square root of 1632.65

Result:

V \approx 40.41
