Compare calculators

Both calculators run independently — change the inputs on either side to compare results.

Bernoulli Equation Calculator

Solve Bernoulli's equation to find downstream pressure in a flowing fluid given upstream conditions, elevation change, and system losses. Used in pipe system analysis, nozzle design, and pump selection.

Fluid Mechanics

Pipe Flow Velocity Calculator

Find the average velocity of fluid flowing inside a circular pipe from the volumetric flow rate and pipe diameter. Essential for checking whether flow falls within recommended velocity limits to avoid erosion or excessive head loss.
