Hello Clever People.
I've conducted tests to determine the pressure drop across a feature using kerosene as the incompressible fluid. I need to to convert the pressure drop I recorded into a pressure drop with ethylene glycol. (We have a kerosene test rig but no glycol test rig.)
The equation I have worked out (assuming turbulent flow) is.
K = [kinematic viscosity of glycol/kinmatic viscosity of kerosene]^.25 x [density of glycol/density of kerosene]
It seems to make sense. Pressure drop increases with kinematic viscosity and density at a particular mass flow rate. I'm asking for confirmation of this equation - it may be that someone else has done something similar themselves.
Thanks in advance!
