Flow Rate Pressure Calculator

Formula

The formula to calculate the Final Pressure (P2) is:

\[ P2 = P1 + 0.5 \cdot p \cdot (v2^2 - v1^2) \]

Where:

\(P2\) is the final pressure
\(P1\) is the initial pressure
\(v2\) is the final velocity
\(v1\) is the initial velocity
\(p\) is the density

Flow Rate Pressure Definition

A flow rate pressure is defined as the pressure differential that arises from the flow of a fluid through a constrained area.

Example Calculation

Let's assume the following values:

Initial Pressure (P1) = 1000 Pa
Initial Velocity (v1) = 5 m/s
Final Velocity (v2) = 10 m/s
Density (p) = 1.2 kg/m³

Using the formula to calculate the Final Pressure (P2):

\[ P2 = 1000 + 0.5 \cdot 1.2 \cdot (10^2 - 5^2) = 1000 + 0.5 \cdot 1.2 \cdot (100 - 25) = 1000 + 0.5 \cdot 1.2 \cdot 75 = 1000 + 45 = 1045 \, \text{Pa} \]

The Final Pressure (P2) is 1045 Pa.
