Question

10) Your body has an average surface temperature of approximately 99°F. Calculate the power per unit area released by your body using Stefan-Boltzmann Law and report the value below. Units are a must. (2 points)

Power per unit area released by your body=

Answer 1

Power per unit area released by the body is
`526.18 Watt/m^2`.

Step-by-step explanation:

Stefan-Boltzmann Law is given as:

`(Power)/(Area)=\sigma T^4`

Where:

`\sigma =5.6704* 10^(-8) Watt/m^2K^4` Stefan-Boltzmann constant

T = Absolute temperature of the body

The body has an average surface temperature of approximately,T= 99°F

T= 99°F

`(T(K)-273.15)=(T(^oF)-32)* (5)/(9)`

`T(K)-273.15=((99)-32)* (5)/(9)`

T = 99°F= 310.37 K

Power per unit area released by the body:

`=5.6704* 10^(-8) Watt/m^2K^4* (310.37 K)^4=526.18 Watt/m^2`
