This calculator can be used to calculate expansion volume when initial volume and initial and final densities for the liquid are known. Specific heat is just the amount of thermal energy you need to supply to a sample weighing 1 kg to increase its temperature by 1 K. Why is my mashout temperature not exactly 170F? Mashout volume is difficult to calculate for BIAB so I calculate a boiling water mashout volume of 30% of the total mash water volume.
