For the streamline flow of an ideal (non-viscous and incompressible) fluid, the sum of pressure energy, kinetic energy, and potential energy per unit volume remains constant at every point along the flow.
P1+12ρv12+ρgh1=P2+12ρv22+ρgh2space cap P sub 1 plus one-half rho v sub 1 squared plus rho g h sub 1 equals cap P sub 2 plus one-half rho v sub 2 squared plus rho g h sub 2
Explicitly define your variables at the beginning (e.g., "Let be the mass, be the initial velocity...").
