Good Morning.



Could you please help with some technical advice?



We are about to flush 30 mtr sections of 2” id tube with a water glycol based fluid namely Oceanic HW 540E, but are having questions relating to what flow rates are required to achieve turbulent flow, we have calcs for hydraulic oil but there seems to be vast differences between the flow rates.

Calculate:
----------
Re-Reynolds Number (till 2000-Laminar Flow , over 2500 Turbolent Flow)
v - Fluid Speed (meter/sec)
ל - Fluid Kinematic Viscosity (meter sq./sec)
D - Tube Wet Diameter (meter)
Q - Flow (meter power of 3/sec)
A - Tube Area (Meter sq.
The Equation.
-------------
Re = v x D / ל , v = Re x ל / D , Q = v x A

Now youcan calculate the required turbolent flow
but you must know the kinematic viscosity of your fluid.

Equation is correct for metric units.
