Calculates the distillate flow rate from the heating power.
It is possible to switch between ml/min, g/min, lt/h, kg/h and mol/h and between %abv, %abw and %abm (percent alcohol by volume, by weight and by mol).
The calculated values do not take into account any heat loss due to, for example, imperfect insulation.
The real distillate flow rates are therefore significantly smaller in practice.
