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 30C, where 0.5g/min of water are evaporated. (a) Does heat need to be added or removed to compensate for the water evaporation? (b) What is the resulting heat load (W) on the fermentor
