Reynolds Number Table: Reynolds number by Fluid density

Reference table of reynolds number for Reynolds Number across a range of fluid density values — exact, engine-computed figures you can read off at a glance.

This reynolds number reference table shows the reynolds number for a range of fluid density values, assuming a flow velocity of 2 m/s, a characteristic length of 0.1 m and a dynamic viscosity of 0.001 Pa·s. Every figure is computed with the same engine that powers our Reynolds Number Calculator, so the numbers are exact.

How to use this table

Find the row closest to your fluid density and read across to the reynolds number. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Reynolds Number Calculator for a precise answer.

Need a value that is not in the table? — the Reynolds Number Calculator does it instantly, for free, with the formula and a worked example built in.

Frequently asked questions

Each cell is computed with the standard formula using exact arithmetic — the same calculation behind our Reynolds Number Calculator — so every figure is accurate for the stated assumptions.

Yes. The table covers common fluid density values; for any exact figure, enter your own numbers in the Reynolds Number Calculator.
