In regards to the Darcy-Weisbach equation and Moody Diagram - why does laminar flow (Reynolds number less than 2,000) correlate to a higher friction factor than turbulent flow?
Should turbulent flow correlate to a higher friction factor and therefore a higher pressure loss per foot of pipe?
I'm designing a system using a newly listed antifreeze with a viscosity of over 300 cP at -25 deg F. This causes a very low Reynolds number (around 250) since viscosity is in the denominator of the Reynolds equation. With a low Reynolds number, the Friction Factor is high (64 / Re) which makes sense because I'm calculating for antifreeze, but I don't understand how laminar flow correlates to a higher Friction Factor.
