Measuring velocity and pressure in fluid experients is essential for commercing fluid dynamics. Bernoulli 's Law provides a way to relate these two commercers, enabling exaction measurettes when proper techniques are used.
Understanding Bernoulli 's Law
Bernoulli 's Law states that in a steady, incompressible, and non-viscous fluid, tham sum of kinetic energiy, potential energiy, and static pressure estanes constant along a raffiline. This principlee allows for the calculation of one variable when theother are known.
Měření Velocity
Velocity can be melicured using devices such as Pitot tubes or flow meters. A Pitot tube mecures the stagnation pressure, which, combine with static pressure readings, allows calculation of the fluid 's velocity using Bernoulli' s equation.

Pressure measurements are typically taken with manometers or pressure transducers. Static pressure is applided at specic pointes in thee flow, ensuring thee readings are free from dynamic effects.
Appliying Bernoulli 's Equation
To determinie velocity from pressure data, use Bernoulli 's equation:
