The formula to calculate the Reynolds Number (Re) is:
\[ Re = \frac{\rho \cdot u_{\text{Fluid}} \cdot D_{\text{Tube}}}{\mu_{\text{viscosity}}} \]
Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities.
Let's assume the following values:
Using the formula:
\[ Re = \frac{400 \cdot 12 \cdot 1.1}{1.02} \approx 5176.47058823529 \]
The Reynolds Number is approximately 5176.47058823529.
