Calculation results, breathing by the mouth during an exercise.

	Case	Qinsp (l/min)	tw (s)	P (J/s)	W (l/day)	$\overline{\eta }$ (-)	η (-)	Emax (μm/min)
V ($•$)	At rest	15	2,000	6.6	0.22	0.58	0.61	6.3
VI ($•$)	Exercise	30	1,000	12.9	0.43	0.56	0.60	11.7
VII ($•$)	Exercise	60	900	23.1	0.79	0.50	0.55	17.9
VIII ($•$)	Exercise	120	800	41.2	1.44	0.45	0.50	24.6
IX ($•$)	Exercise - cold	120	800	66.0	1.67	0.46	0.44	20.7

All the results are obtained using an ambient air at 27°C and at a relative humidity of 40%, except for case $•$, where an ambient air at 5°C and at a relative humidity of 1% is used. E_max is the highest value of the time averaged evaporation rate, which is calculated in the fourth generation for all the calculations.
