=Batch_Size-((total_wort)-Kettle_Loss-((Boil_Loss/60)*Boil_Time))

My formulae are getting longer and my heads battered.

Now my head is hurting.

What the formula for effieciency?


Say I know that the predicted SG is 1050 @ 70% effieciency on 30l run off.

I have 1045. How do I work out my effieciency?

It would be your 1045 divided by the predicted gravity, before your efficiency correction.

.0714 * y = .045

But you efficiency looks different than mine. I may be over simplifying it.

=((Gravity_per_lb_per_gallon-1)*LBS_added/Gallons)*Estimated_Efficiency

45/50*70

0.9*70

63%

Is that what you mean?


Not sure how that relates to .0714 * y = .045

No.

y = .045/.0715 = .6294 or 63%

Where does the .0715 come from.

Doing it my way I got 63% same as you.

Thats 100% efficiency. Most of the stuff I've found on different malts and grains gives you the gravity at 100% then you reduce it.

Take the formula from my spreadsheet. I can't seem to find the original spreadsheet link from BYO where I got mine, but mine came right from that.
