How do you measure velocity pressure with a pitot tube? Formula for calculation The formula to calculate velocity using Bernoulli’s equals is provided below. V is equal to sqrt (2*(static pressure minus stagnation pressure)/density). To calculate the flow velocity (v), you need the values of static pressure (P), density (ρ), and stagnation pressure (P0). Rearranging …
