## About Flow Rate Pressure Calculator (Formula)

The Flow Rate Pressure Calculator is a tool designed to calculate the final pressure of a fluid moving through a duct. It is based on a specific formula that relates the initial pressure, initial velocity, final velocity, and density of the fluid.

The formula used in the calculator is:

P2 = P1 * 0.5 * ρ * (v2^2 – v1^2)

Where:

• P2 is the final pressure of the fluid.
• P1 is the initial pressure of the fluid.
• ρ (rho) represents the density of the fluid.
• v2 is the final velocity of the fluid.
• v1 is the initial velocity of the fluid.

In the formula, the difference between the squares of the final and initial velocities is multiplied by half the density and the initial pressure. The result gives the final pressure of the fluid.

By providing the values for the initial pressure, initial velocity, final velocity, and density in the Flow Rate Pressure Calculator, you can obtain the calculated final pressure of the fluid flowing through the duct. This calculation is useful in various engineering and fluid dynamics applications, helping to understand and predict the behavior of fluids under different conditions.
