Flow and pressure equation

Web2 days ago · The Formula given by Bernoulli under this principle to explain the relation of pressure and velocity is: P + 1 2 ρ v 2 + ρ g h = Constant. In the above formula, P denotes the pressure of the in-compressible, non-viscous fluid that is measured using N/m2. ρ denotes the density of the non-viscous liquid, which is measured using Kg/m2. WebDec 14, 2024 · Rearranging the equation gives Bernoulli’s equation: (14.8.4) p 1 + 1 2 ρ v 1 2 + ρ g y 1 = p 2 + 1 2 ρ v 2 2 + ρ g y 2. This relation states that the mechanical energy of any part of the fluid changes as a result of the work done by the fluid external to that part, due to varying pressure along the way.
