Enter the surface area and the temperature difference into the calculator to determine the body heat loss.
Body Heat Loss Formula
The following formula is used to calculate the body heat loss for a given surface area and temperature difference.
Q = A * ΔT * 5.67 * 10^-8
Variables:
- Q is the heat loss in watts
- A is the surface area in square meters
- ΔT is the temperature difference in degrees Celsius
To calculate the body heat loss, multiply the surface area by the temperature difference and then multiply the result by the Stefan-Boltzmann constant (5.67 * 10-8 W/m²K⁴).
What is Body Heat Loss?
Body heat loss refers to the process by which the human body loses heat to its surroundings. This can occur through various mechanisms such as radiation, convection, conduction, and evaporation. The rate of heat loss is influenced by factors such as the surface area of the body, the temperature difference between the body and its environment, and the thermal properties of the surrounding medium. Understanding body heat loss is important in fields such as medicine, sports science, and environmental physiology, as it helps in designing appropriate clothing, medical treatments, and living conditions to maintain thermal comfort and prevent conditions like hypothermia or hyperthermia.
How to Calculate Body Heat Loss?
The following steps outline how to calculate the Body Heat Loss.
- First, determine the surface area of the body (A).
- Next, determine the temperature difference between the body and its environment (ΔT).
- Next, calculate the heat loss using the formula Q = A * ΔT * 5.67 * 10-8.
- Finally, calculate the Body Heat Loss.
- After inserting the values and calculating the result, check your answer with the calculator above.
