Document Summary

Section 3. 06: examples of use of the bernoulli equation. Italian physicist, torricelli: the exit pressure for an incompressible fluid jet is equal to the surrounding pressure, this fact that the exit pressure equals the surrounding pressure is seen by applying. F=ma: physically, there is no component of acceleration of the weight force in the horizontal direction, therefore the pressure is constant in that direction, outside the nozzle we get the equation below. H represents the distance the fluid has fallen outside the nozzle: v can also be written as the equation below. The water leaving the spout can be thought of i(cid:374) a si(cid:373)ilar way. This is co(cid:374)siste(cid:374)t with the fact that all of the particle"s pote(cid:374)tial energy is converted to kinetic energy, providing a viscous friction effect that is negligible. Confined flows: the continuity equation states that mass cannot be created or destroyed.
