This equation can be derived from the conservation of energy, and it contains terms corresponding to the kinetic and potential energies for fluids.
A specific case of this equation sets velocity equal to the square root of 2gh. Venturi meters and pilot tubes measure velocity using this equation, which is only applicable to compressible substances with low Mach numbers. This equation is expressed as Torricelli's theorem when pressure is constant. This equation can be derived from the conservation of energy, and it contains terms corresponding to the kinetic and potential energies for fluids. It explains the net upward force experienced by airplane wings, known as dynamic lift. For 10 points, name this equation that states that an increase in the speed of a fluid is accompanied by a decrease in pressure, named for a Swiss scientist.
A specific case of this equation sets velocity equal to the square root of 2gh.
