Web8.1 Introduction. The flow equations presented in Chapter 7 are generally nonlinear. To obtain the pressure distribution in the reservoir, these equations are linearized in order to use linear equation solvers. In this chapter, we aim at obtaining the linearized flow equation for an arbitrary gridblock (or gridpoint). WebNov 5, 2024 · The SI unit of flow rate is m 3 /s, but other rates can be used, such as L/min. Flow rate and velocity are related by Q = Av where A is the cross-sectional area of the flow and v is its average velocity. The equation of continuity states that for an incompressible fluid, the mass flowing into a pipe must equal the mass flowing out of the pipe.

WebAgain, setting λ = 0 gets us back to the typical form of Euler’s equations found in textbooks on inviscid flow. Bernoulli’s Equation. One useful relation for understanding incompressible steady flows is Bernoulli’s equation. This equation relates the energy (kinetic and potential) per unit mass of a fluid to its static pressure.
