Connects pressure, speed, and height along a flow — the physics behind airplane wings and venturi effects.
Bernoulli's equation says that along a streamline, as fluid speeds up, its pressure drops (all else equal) — this is the basic idea behind how an airplane wing generates lift and why a shower curtain gets pulled inward by fast-moving water.
This calculator, like the classic Bernoulli equation, assumes the fluid is incompressible and has no viscosity (no internal friction) — real fluids like air and water depart from this ideal to varying degrees, especially at high speed or in turbulent flow.

P₂ = P₁ + ½ρ(v₁² − v₂²) + ρg(h₁ − h₂)
What you entered
P₂ = P₁ + ½ρ(v₁² − v₂²) + ρg(h₁ − h₂)
101325 + 0.5×1000×(2²−5²) + 1000×9.81×(5−0)= 139875 PaResult
Pressure at point 2 (Pa): 139,875
Using Bernoulli's equation, pressure at point 2 works out to 139,875 Pa.
