Sparge Water Formula

[mrgbrewer]

Hello,

does anyone have a complete batch sparge formula that includes the following parameters?:

• grain absorption
• dead space
• desired wort volume
• grist
• mash volume
• boil off during boiling (so we know what volume of wort we should have before boiling)

Here's a formula I've been using so far that did work for my brew but I would like to add the parameters above so my next brew is more precious:

*Is the Boil Time (hrs) even needed in the formula when it does not account the volume of water evaporated during boiling?

Thanks to everyone in advance!

Sparge water volume is equal to Total Water minus Strike Water. To get Total Water volume needed...

Desired batch size into the fermenter
+ grain absorption
+ unrecoverable mash tun dead space
+ tun to kettle transfer losses
+ kettle hop/trub absorption
+ boil off
+ kettle to fermenter transfer losses.
