Under steady conditions, the rate at which the water leaves the make-up tank is equal to the rate of evaporation plus any small airborne droplets in the air discharge (i.e., drift)

Please write energy balance for the system of trial 1 and 1 column and validate the equation.

Can you also explain how to calculate the %difference for the three experiments and comment on the observed trend?

Hint: mass flow rate of air =0.0137*[x/(1+2)*specific volume]^0.5, unit of x is mmH2O
