What would be the SG formula for dilution? If I had 5 gallons of 1.050 and added 0.5 gallons of water, how would I calculate the resulting SG?

Don,
It should work out something like this: (sg x vol) + (sg x vol) = new sg x total vol. That is, (1.050 x 5) + (1.000 x.5) = new sg x 5.5 That comes out to
5.75 = 5.5 x new sg or 1.045 = new sg
Simple way to look at it is that 1.050 means you have 50 points per gallon. Given 5 gallons, you have a total of 250 points. When you add 1/2 gallon of water, you still have the 250 points, but now they are spread across 5.5 gallons.
250 points / 5.5 gallons = 45.4545... points per gallon. So your new SG is 1.0455.Dick
Thanks Mike and Dick, both answers were what I was looking for.
