In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.

The Bernoulli equation states that

where;

The principle is only applicable to isentropic flows. The equation is not valid when the flow is turbulent (the effect is irreversible) and for non-adiabatic processes (e.g. thermal radiation) because the effect is small.

Bernoulli equation can of course be rearranged to solve for each variable. Below presents a calculation to solve for q.
