I though i was distracting you...

...alas i wasn't. I am actually awaiting for the completion of the below formula....

V = d2 (S - S1) g

18µ

where:
V = the velocity of precipitation
d = the floc diameter
S = the floc density
S1 = the beer density
g = gravitational constant
µ = the beer viscosity coefficien

so as you can see some days i do some really fun stuff. Right on to tax chat with HMRC.

Cheers all JK
