Default Compensating for grains and water absorption?

Hey folks, just bought the beer smith app and like it a lot but I feel I am missing something and a calculation I completely forgot to do when I was making my first batch of all grain last weekend. I had to add more water to my sparge to get the volume I needed, 5 gallons of pale ale wort, and wanted to know how I go about calculating, for example, what 12.5 grains of 2-row will chew through and absorb once the water hits.

I am brewing a seasonal ale from midwest supplies, the Seasonal Happy Ale, and its 12.5 pounds. Going for the 152 degree mash temp and thats about it for now. Any help guys? Thanks..

Are you asking what typical grain absorbtion is? The most common number I see is 0.5 quarts per pound, so for 12.5 pounds that's about 1.5 gallons.

BeerSmith will give those numbers on the recipes' "Vols" tab. It will also tell you how big your MLT needs to be.
