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
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.
