The heat rate from radiation heat transfer is measured to be 16260 W for an area of 0.375 m² when the temperature of the blackbody is equal to 325 °C and the temperature of the surroundings is equal to 1290 °F. What are the SI units of the Stefan- Boltzmann constant and what is the numerical value based on the data from this experiment? The SI units of o are (choose one) O W/K4 O K4/(W-m²) O (K4-m²)/W O W/(m².K²) O W/(m2.K4) What is the numerical value of σ in those units? i There are three modes of heat transfer: conduction, convection, and radiation. Each has an empirical law that relates the rate of heat transfer, q (W), to a temperature difference driving force. The rate law for radiation is known as the Stefan-Boltzmann Law. For a black-body, the Stefan-Boltzmann Law is: 9=0A(TT) In this equation, q is the rate of heat transfer (W), σ is the Stefan-Boltzmann constant, A is the area (m2), T is the temperature of the material, and Tsurr is the temperature of the surroundings.

Help with the following question please show all steps.
Transcribed Image Text:The heat rate from radiation heat transfer is measured to be 16260 W for an area of 0.375 m² when the temperature of the
blackbody is equal to 325 °C and the temperature of the surroundings is equal to 1290 °F. What are the SI units of the Stefan-
Boltzmann constant and what is the numerical value based on the data from this experiment?
The SI units of o are (choose one)
O W/K4
O K4/(W-m²)
O (K4-m²)/W
O W/(m².K²)
O W/(m2.K4)
What is the numerical value of σ in those units? i
Transcribed Image Text:There are three modes of heat transfer: conduction, convection, and radiation. Each has an empirical law that relates the rate of heat
transfer, q (W), to a temperature difference driving force. The rate law for radiation is known as the Stefan-Boltzmann Law. For a
black-body, the Stefan-Boltzmann Law is:
9=0A(TT)
In this equation, q is the rate of heat transfer (W), σ is the Stefan-Boltzmann constant, A is the area (m2), T is the temperature of the
material, and Tsurr is the temperature of the surroundings.
