OK. So, I'm trying to figure out the water:grain ratio in my stainless BIAB basket when it is installed in my kettle. There is space OUTSIDE the basket and space inside the basket. The basket will obviously have grain AND wort, while the space outside the basket will only be wort.
Basically what I'm trying to figure out is an easy(ish) way to calculate the water:grain ratio INSIDE the BIAB basket, NOT the total water:grain ratio in the entire pot. Is there a way to figure this out? And if so, is there an Excel calculation I can write where I supply certain numbers (i.e. amount of grain, water, etc.).
I want this because if possible, I'd like to target a particular water:grain ratio in the basket for the mash and then at the end of the mash add the remaining water (if any) to get my full volume before removing the basket.
How can I figure this out?
The BIAB Basket is shaped like a D (see picture). Here are the measurements:
BIAB Basket Height - 13"
BIAB Basket Diameter - 11"
BIAB Basket Segment Depth - 9"
Total Space Available - ≈4.68gal according to this calculator:

The Brew Pot is a 7.5gal Blichmann Boilermaker G2. It's internal dimensions are:
Pot Height - 14.75"
Pot Diameter - 12.3"
According to Blichmann when this pot is full to the brim there is ≈7.4gal of space available.
There is a "step" at the bottom that reduces the diameter to 9.25". This step is ≈5/8" tall.
If it helps, when I have the BIAB basket installed there is ≈.4375gal of water underneath the basket (i.e. Foundation Water).
Make sense? If not...I can supply other measurements/numbers/info/explanations/etc.
