Bernoulli's Equation Calculator
Use this calculator to apply Bernoulli’s principle to compute pressure, velocity, or elevation differences between two points in an ideal fluid flow system.
What this calculator is doing
Bernoulli's Equation describes the conservation of mechanical energy in a fluid flow and relates pressure, kinetic energy, and potential energy between two points:
\[ P_1 + \frac{1}{2} \rho v_1^2 + \rho g h_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g h_2 \]
Where:
\( P \) = Pressure (Pa)
\( \rho \) = Fluid density (kg/m³)
\( v \) = Flow velocity (m/s)
\( g \) = Acceleration due to gravity (9.80665 m/s²)
\( h \) = Elevation head (m)
This calculator solves for the missing pressure, velocity, or height between two points given the rest of the values. It assumes incompressible, steady, and frictionless flow.
