# Bernoulli Force

Bernoulli’s equation, which was named for Daniel Bernoulli, relates the pressure in a gas to the local velocity; so as the velocity changes around the object, the pressure changes as well. What’s the problem? Bernoulli’s equation is used on aircraft to provide a speedometer called a pitot-static tube. A pressure is quite easy to measure with a mechanical device. In a pitot-static tube, we measure the static and total pressure and can then use Bernoulli’s equation to compute the velocity. Ask – How fast is this airplane going? It is moving through the air at some speed. The air itself … Continue reading Bernoulli Force
