A 75 kg cyclist rides their bike at 15 km/h. The air temperature outside is the same as that of the skin, approximately 34C.

A 75 kg cyclist rides their bike at 15 km/h. The air temperature outside is the same as that of the skin, approximately 34∘C. The power consumption during this exercise is 300 W and the body's net efficiency in converting metabolic energy into cycling energy is approximately 25%. How many grams of water must the cyclist evaporate by sweating, each minute, just to stay at the same temperature? (The latent heat of vaporization of water is ~2.25×10^6 J/kg)
