I have 12500 Litre =106.6 bbl (US) Brewlength. How to set equipment profile for the same.
Whenever I commission a new brewhouse, I start with a series of water batches to sort out volumes, flow and temperature losses. If you start with a known volume of water and run it through each vessel as if brewing, you'll have a final volume that is less than what you started. This will tell you the losses accumulated and you can just input those numbers into the equipment profile you create for your system.
So, the difference between what you add to the mash/lauter (either single vessel of mash cooker. lauter combo) and what you collect in the boil kettle are your "Lauter Tun Losses." If you have to add foundation water to the lauter or cooker and that water is later collected to the kettle, the amount is entered as "Mash Tun Addition."
Similarly, the difference between post boil kettle volume and what you collect in a fermenter gets entered as "Loss to Trub and Chiller." When the percentage of fermenter volume to the post boil kettle volume is what you multiply by your expected mash efficiency to get brewhouse efficiency.
These will rough you in and then you can refine your numbers based on actual results for absorption, trub, and yield.
