An average human produces about 10 MJ of heat each day through metabolic activity. If a human body were an isolated system of mass 65 kg with the heat capacity of water, what temperature rise would the body experience? Human bodies are actually open systems, and the main mechanism of heat loss is through the evaporation of water. What mass of water should be evaporated each day to maintain constant temperature? Assume that the body temperature is 37 °C. Use the thermodynamic tables in Perry's Chemical Engineering Handbook 8th Edition.

Question
Transcribed Image Text:An average human produces about 10 MJ of heat each day through metabolic
activity. If a human body were an isolated system of mass 65 kg with the heat capacity of
water, what temperature rise would the body experience? Human bodies are actually open
systems, and the main mechanism of heat loss is through the evaporation of water. What
mass of water should be evaporated each day to maintain constant temperature? Assume
that the body temperature is 37 °C. Use the thermodynamic tables in Perry's Chemical
Engineering Handbook 8th Edition.
