WATER_reynoldsnumber_re(): Reynolds number

About:

Calculate the flow Reynolds number.

\begin{equation} Re = \frac{V \times d}{\nu} \end{equation}

Where,

$V$, flow velocity - $\frac{m}{s}$;

$\nu$ , water kinematic viscosity » WATER_viscosity_kvisc(), $\frac{m^2}{s}$

Module: WaterProperties

Function: WATER_reynoldsnumber_re(q,d,t,s)

Definition of variables:

• q, flow - m3/s;
• d, internal diameter - m;
• t, temperature - ºC;
• s, water salinity - g/kg

Sample code:

from WaterProperties import *

q = 1.0 #(m3/s)
d = 0.75 #(m)
t= 15 #(oC)
s=2.5 #(g/kg)
re = WATER_reynoldsnumber_re(q,d,t,s)
print ("Re:",re)
