In a biological system, N2 is often bubbled through a fermentor to maintain anaerobic conditions.
As the N2 bubbles through the fermentor, the gas strips water from the liquid. Consider an isothermal continuous fermentation process operated at 30°C, where 0.5 g/min of water are evaporated.

(a) Does heat need to be added of removed to compensate for the water evaporation?

(b) What is the resulting heat load on the fermentor?
