Instantly convert pressure to velocity using our accurate Pressure to Velocity Calculator. Enter pressure and density to get fluid speed easily and fast.
Understanding how pressure converts into velocity is important in physics, engineering, and fluid mechanics. That’s why we created a Pressure to Velocity Calculator that helps users instantly convert pressure into velocity without any complex math. Whether you're a student, engineer, or just curious, our tool uses accurate formulas to calculate velocity from pressure easily.
In physics, pressure and velocity are strongly related, especially in fluids like air or water. When the pressure of a fluid changes, the speed of the fluid also changes. According to Bernoulli’s principle, when pressure decreases, velocity increases. This is why pressure and velocity are often said to have an inverse relationship.
The most commonly used formula to convert pressure into velocity is:
v = √(2 × ΔP / ρ)
Where:
This formula comes from Bernoulli’s equation used in a pitot tube or dynamic pressure calculation. It allows us to find the speed of a fluid using only pressure and density.
Our calculator uses the exact same pressure to velocity formula used in physics and engineering. You just enter the total and static pressure (or direct dynamic pressure) and the fluid density. The tool instantly does the calculation and shows the velocity in meters per second.
When a fluid moves faster, the pressure inside it becomes lower. That is why high velocity equals low pressure, and high pressure equals low velocity. This is easy to see in a pipe or airflow system. This is the reason airplanes use pitot tubes to measure air velocity using pressure difference.
Converting pressure to velocity is not as difficult as it sounds. With the right formula, you can easily calculate the velocity of any fluid by simply knowing the pressure difference and density. Our Pressure to Velocity Calculator is made for users who want fast and accurate results. Whether you’re studying physics, working in mechanical engineering, or working on a science project, this tool will help you convert pressure to velocity instantly and correctly.
You can calculate velocity by using the formula v = √(2 × Pressure Difference ÷ Density). Enter the pressure difference in Pascals and divide it by the fluid density, then take the square root.
Pressure and velocity are inversely related in fluid dynamics. As velocity increases, pressure decreases, and when velocity decreases, pressure increases.
Our calculator uses the Bernoulli-based equation: Velocity = √(2 × ΔP / ρ).
Force and velocity are different physical values. Pressure is force per unit area, so you must convert force into pressure and then use the velocity formula.
Due to conservation of energy in a fluid, energy of pressure converts into kinetic energy. So when velocity goes up, pressure must go down to keep the total energy constant.
