How should you ensure you are in the valid range of Reynolds number to apply the Darcy's Law correctly? 2D. Consider a porous medium with the following rock properties • Porosity, Ø = 20% • Permeability, k = 200 mD The fluid being injected into the medium at a Darcian velocity, u = 5 cm/s, has the following properties...
Blasius equation for turbulent flow f = 0.316Red-1/4 holds good only when the Reynolds number is in the range ____________.
Recall that the Reynolds number is a dimensionless number that we use to discuss the flow charecteristics of moving fluids. Generally speaking it is the ratio of momentum forces to viscous forces, and it depends on the diameter of the pipe, the density of the fluid, the velocity of the moving fluid, and the viscosity of the moving fluid. It is normally given by Re Where Re - Reynolds number [dimensionless) p- fuid density v- fud velocity D- pipe diameter...
