Compare calculators
Both calculators run independently — change the inputs on either side to compare results.
Fluid Mechanics
Bernoulli's Equation Calculator
Compute the total mechanical energy per unit volume of a flowing fluid at a point by summing static pressure, kinetic pressure, and elevation head. Useful for analyzing pipe flow energy, sizing nozzles, computing venturi meter response, and explaining lift on airfoils.
