Pressure to Velocity Calculator


About Pressure to Velocity Calculator (Formula)

A Pressure to Velocity Calculator is a tool used to convert pressure measurements to corresponding velocity values in fluid dynamics and engineering analyses. This calculator is particularly useful when working with fluid flow, whether it’s in pipes, channels, or other systems. The conversion between pressure and velocity is often done using Bernoulli’s equation, which describes the relationship between pressure, velocity, and potential energy in fluid flow.

The general formula for converting pressure to velocity using Bernoulli’s equation is:

Velocity (v) = √((2 * (Pressure Difference) / Fluid Density))


  • Velocity (v): The velocity of the fluid in the system.
  • Pressure Difference: The difference in pressure between two points in the fluid flow.
  • Fluid Density: The density of the fluid.

Keep in mind that this formula assumes incompressible and steady flow, as well as neglects losses due to friction and other factors.

For example, if you have a pressure difference of 1000 Pa (Pascals) between two points in a fluid flow with a fluid density of 1.2 kg/m³, the velocity would be:

Velocity (v) = √((2 * 1000 Pa) / 1.2 kg/m³) ≈ 36.74 m/s

This means the fluid is flowing at a velocity of approximately 36.74 meters per second.

The Pressure to Velocity Calculator simplifies this conversion process, making it easy to interpret and use pressure measurements to understand fluid flow characteristics. However, it’s important to consider the assumptions and limitations of Bernoulli’s equation when applying this formula to real-world situations.
