Understanding Bernoulli's equation
Thread Content
How should potential energy, kinetic energy, and pressure energy be understood in Bernoulli’s equation? Is the unit of pressure energy the same as that of potential energy and kinetic energy? Is the flow meter based on the principle of Bernoulli’s equation?

All the units are of length dimension. There are many principles behind flow meters, and it depends on the type of flow meter: for example, mass flow meters operate based on the Coriolis force principle, pressure difference type flow meters are governed by the Bernoulli principle, while vortex flow meters function according to the Karman vortex street principle.
