Default Grain absorption

Is there a rule of thumb to how much water will be lost to grain absorption while mashing? I'm trying to figure out how much water I'd need at mash out. Strike volume is 14.13 Quarts...basically 3.5 gallons. How much of that water would I have left after a 60 min mash? Will pro mash calculate that?

In my experience it seems to average around 1 gallon per 10 lbs of grain.

Assuming you mean your sparge water 170-180 is a good range
