Enter the velocity of flow (m/s) and the density (kg/m^3) into the calculator to determine the Pressure From Velocity. 

Pressure From Velocity Formula

The following formula is used to calculate the Pressure From Velocity. 

P = V^2*d / 2

  • Where P is the Pressure From Velocity (pascals)
  • V is the velocity of flow (m/s) 
  • d is the density (kg/m^3) 

How to Calculate Pressure From Velocity?

The following two example problems outline how to calculate the Pressure From Velocity.

Example Problem #1:

  1. First, determine the velocity of flow (m/s). In this example, the velocity of flow (m/s) is given as 53.
  2. Next, determine the density (kg/m^3). For this problem, the density (kg/m^3) is given as 34.
  3. Finally, calculate the Pressure From Velocity using the equation above: 

P = V^2*d / 2

Inserting the values from above and solving the equation: 

P =53^2*34 / 2 = 47753 (pascals)


Example Problem #2: 

Using the same process as above, first define the variables required by the formula. In this case, these values are:

velocity of flow (m/s) = 83

density (kg/m^3) = 13

Entering these values yields:

P = 83^2*13 / 2 = 44778.5 (pascals)
