WebDimensionless Number Lionel A. Sequeira, P.E. Introduction So you’ve been tasked with finding the pressure drop in a simple piping system. You know the pipe diameter, the fluid density, and even the flow rate. You find a formula for the Reynolds Number in your reference material; Re = ρvD/μgc. You know you need the Reynolds Number to

The Reynolds number is the ratio of inertial forces to viscous forces within a fluid that is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe. A similar effect is created by the introduction of a stream of high-velocity fluid into a low-velocity fluid, such … nj notary answersWebThe mainstream velocity is the velocity outside of the boundary layer. Since the Reynolds number depends on the density of the ideal gas, the same assumptions for ideality apply in our calculations. The program 'recalc' uses rhocalc and mucalc to determine the density and viscosity respectively which are then used to calculate the Reynolds number. nj notary expirationWebJul 18, 2013 · Depending on how ideally the two fluids mix, you may want to look up or calculate the actual properties of the particular mixture you're working with.
