Flow and pressure equation
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. WebMar 17, 2016 · In order to calculate the average velocity or the flow rate, you need to determine, whether the flow is laminar or turbulent, and also calculate the friction coefficient. The pressure drop in a circular pipe is given by : $$\Delta P = \lambda \cdot \frac{L \cdot\rho}{2 \cdot D}\bar{u}^2$$ where: $\lambda $ is the pipe friction coefficient (See ...
