This should give you about 12.7 gallons in the boil kettle.
By my calcs, this won't fit in your 10-gal MLT...6 gallons H2O + 24 lb grain needs ~8 gallons of space, so there's no room for 3.25 gal of mashout H2O.
One option might be to:
- mash with 1.1 qt/lb, skip the mashout, drain the MLT
- do a 4-gal batch sparge
- do another 4-gal batch sparge
If your absorption is 0.1gal/lb, this gives you 4.2 + 4.0 +4.0 = 12.2 gal in your brewpot. As others have said, you might want to sparge more for better efficiency; could probbly go with a mash of 1.25 qt/lb (will be tight) and then maybe 5 gal for each sparge.
