Mashing and Fly Sparring

donsmitty:
I just completed my first all-grain brewing and did a fly sparging.  14.45 lb of grain were in the tun along with 4.75 gal of water.  My sparge water was 4 gallons.  Given my target was to have 6 gallons pre-boil, was I OK using the volumes I did?  And, how long would you take to complete the sparging?  The numbers were from calculations done in BeerSmith.  Reading John Palmer's book, he says to use 2 qts/lb for mashing.  If I did that I would be putting in 7 gallons into the tun and it wouldn't leave much for sparging.  I'm interested in knowing what you do for calculating volume for your mash tun as well as sparging.

Me, I make life easy and batch sparge.  I mash around 1.5-2 qt./lb. , run that off, and sparge with enough to get my boil volume.  Saves me an hour over fly sparging and my efficiency is every bit as good.

How do you decide if it's 1.5 or 2 qt./lb.?  Should the mash and sparge volumes be close to 50/50?

I'm simple, and just try to be 1.5-2 with no thought as to why. I guesstimate my Sparge water amount for boil volume using one gallon per ten pounds grain for absorption

Not the volumes themselves, but the runoffs from the mash and sparge should be close to the same volume.  It's not a big deal if they aren't (within a gal. of each other is usually fine), but the closer the better.  And keep in mind that this is for batch sparging.  Might be different for fly sparging.
