Enter the total dynamic pressure and the fluid mass density into the calculator to determine the velocity.

## Pressure to Velocity Formula

The following formula is used to calculate a velocity from dynamic pressure.

V = Sqrt [ (2*q/p) ]

- Where V is the velocity (m/s)
- q is the dynamic pressure (pascals)
- p is the fluid mass density (kg/m^3)

## Pressure to Velocity Definition

Calculate a velocity from a dynamic pressure requires that you also know the density. Dynamic pressure arises from the movement of fluid through a volume.

## Pressure to Velocity Example

How to calculate velocity from pressure?

**First, determine the dynamic pressure.**Measure the dynamic pressure of the flow.

**Next, determine the density.**Calculate the density of the fluid in movement.

**Finally, calculate the velocity.**Calculate the velocity from the dynamic pressure and density using the equation above.

## FAQ

**What is a dynamic pressure?**

Dynamic pressures are pressure differentials that arise from the flow of a fluid through a constrained area.
