Title: Cfm & lift
Post by: brianbarber on August 04, 2011, 10:55:48 pm

Hi folks

Can somebody explain in simple terms CFM and the "mercury lift" values quoted by machine manufacturers?

Many thanks in advance

Mr B

Imagine you're drinking through a straw.

Lift is how hard you're sucking

CFM is how much drink you end up with in your mouth.





And more importantly why are McDonalds straws so flimsy you can't drink one of their milkshakes through them without the straw collapsing, unless you let it melt, which defies the point of having a milkshake >:(

THey are made that way so that a good chunk of the calories in the shake are offset by the energy required to pull it up the straw.
