Why does this myth prevail?

Fluid dynamics has the Garfield Principle... Fluid flows faster thru a 
short, large catheter...  i.e. a 14G, 1.25" IV.  A central line does not 
allow faster flow of fluids.

For those who want the specifics:  Rate of flow is directly proportional to 
the fourth power of the internal radius of the catheter and inversely 
proportional to the length.

I do understand that not everyone has veins that will take a 14G, but to 
think that a central line is more conducive to rapid infusion is erroneous.
