Why can sweat remain without cooling much?
Fit the specimen and set conditions before running.
Sweat removes latent heat when liquid water becomes vapor. High humidity reduces that outward vapor gradient, so more water can remain pooled on the skin.
Patch model: evaporative capacity=0.8(1+air speed)(1-RH) g/min; this coefficient is illustrative. Latent heat=2400 J/g. No heat-safety prediction.
Evaporate at least 0.5 g/min of sweat from the specimen.
Compare evaporative cooling at different humidities and air speeds.
