Use mash_calc
to calculate mash composition when brewing beer. Use strike
to calculate the strike temperature for hot liquor to achieve a given mash
temperature. The word liquor is used here in the brewing sense to mean water
which is mixed into the mash.

|
ml |
mass of liquor in Kg (or volume in L) |
mg |
mass of grist in Kg |
tm |
temperature of mash in degrees C after mixing |
tl |
temperature of liquor in degrees C before mixing |
tg |
temperature of grist in degrees C before mixing |
shl |
specific heat of liquor relative to pure water. Defaults to 1.0 |
shg |
specific heat of grist relative to the liquor. Defaults to 0.4 |
shw |
specific heat of pure water. This is 4.181kJ/Kg/K |
the missing variable in the equation tm=(shl*tl*ml+shg*tg*mg)/(shl*ml+shg*mg)
