Enter the static pressure (Pa), the fluid density (kg/m^3), and the fluid speed (m/s) into the calculator to determine the Stagnation Pressure.

## Stagnation Pressure Formula

The following formula is used to calculate the Stagnation Pressure.

Pstag = Pstatic + 1/2 * p * v^2

• Where Pstag is the Stagnation Pressure (Pa)
• Pstatic is the static pressure (Pa)
• p is the fluid density (kg/m^3)
• v is the fluid speed (m/s)

## How to Calculate Stagnation Pressure?

The following example problems outline how to calculate the Stagnation Pressure.

Example Problem #1

1. First, determine the static pressure (Pa). In this example, the static pressure (Pa) is given as 10 .
2. Next, determine the fluid density (kg/m^3). For this problem, the fluid density (kg/m^3) is given as  1250 .
3. Next, determine the fluid speed (m/s). In this case, the fluid speed (m/s) is found to be 5.
4. Finally, calculate the Stagnation Pressure using the formula above:

Pstag = Pstatic + 1/2 * p * v^2

Inserting the values from above and solving yields:

Pstag = 10 + 1/2 * 1250 * 5^2 = 15635 (Pa)

Example Problem #2

Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:

static pressure (Pa) = 10

fluid density (kg/m^3) = 500

fluid speed (m/s) = 6

Enter these given values yields:

Pstag = 10 + 1/2 * 500 * 6^2 = 9010 (Pa)
