Calculations are performed using heat balance and mass balance.

As mentioned above, it’s a heat balance calculation. It’s similar to how, by knowing the amount of heating steam at the bottom of a distillation tower, the gas phase flow rate can be calculated.

Sir, it’s by using the latent heat of vaporization, and then calculating the amount of evaporation based on the heat input, right?

Yes, the amount of steam generated by boiling is of course calculated using the latent heat
