Velocity to Pressure Calculator

Formula

The formula to calculate Pressure From Velocity (P) is:

\[ P = \frac{V^2 \times d}{2} \]

Where:

\( P \) is the Pressure From Velocity (pascals)
\( V \) is the Velocity of Flow (m/s)
\( d \) is the Density of the Fluid (kg/m³)

What is Pressure From Velocity?

Pressure from velocity refers to the dynamic pressure exerted by a moving fluid. When a fluid flows with a certain velocity, it exerts pressure on surfaces it contacts. This pressure is related to the fluid’s velocity and density. The calculation of pressure from velocity is important in various fields, including fluid dynamics, aerodynamics, and engineering, where it helps in understanding the behavior of fluids under different flow conditions.

Example Calculation

Let's consider an example:

Velocity of Flow (V): 10 m/s
Density of the Fluid (d): 1.225 kg/m³ (approximate density of air at sea level)

Using the formula to calculate Pressure From Velocity:

\[ P = \frac{10^2 \times 1.225}{2} = \frac{100 \times 1.225}{2} = \frac{122.5}{2} = 61.25 \, \text{Pa} \]

This means that the pressure generated by the flow of air at 10 m/s is approximately 61.25 pascals.
