Input (English): Dividing this equation through by the acceleration of gravity gives you the head equation. This law can be derived by integrating the inviscid Newtonian Navier-Stokes equation along a streamline. It gains a term of the specific internal energy if the flow is compressible. A form of local energy conservation for an ideal fluid, it explains the Venturi effect and some aspects of flight. FTP, name this principle, usually stated as v-squared over two plus p over rho plus g z is constant; a principle of fluid mechanics named for a Swiss mathematician.
Output (English): Science
