In my experience, doing 3-6 reps is the sweet spot for this type of training. As this is done in a circuit fashion with incomplete rest, you'll be unable to perform the same loads as during traditional lifting sessions.
The water on your body changes to a gas called water vapor. Water turns into a gas through a process called evaporation. Heat makes water evaporate faster. All air has some water vapor. Tropical rain forests and deserts are both hot.
The speed water evaporates contributes directly to how much water vapor is in the air, and contributes indirectly to future precipitation. However, the rate of evaporation forms depends on external variables such as temperature, humidity and wind speed.
