Textbook Problem

Objects A and B have the same size and shape with emissivities eA and eB and temperatures TA and TB, respectively. (a) if eA = eB and TB = 4TA, what is the ratio PB/PA of their radiated powers? (b) If, instead, they radiate the same power and eA = 4eB, what is the ratio TB/TA of their kelvin temperatures?

(a)

To determine
The ratio PB/PA of the radiated power.

Explanation

Given Info: Objects A and B have the same size and shape with emissivities eA and eB and temperatures TA and TB respectively.

Formula to calculate the radiated power from object A is,

PA=σAeATA4 (I)

  • PA is the power radiated by the object A
  • σ is the Stefan Boltzmann constant
  • A is the area of the object A and B
  • eA is the emissivity of the object A
  • TA is the temperature of the object A

Formula to calculate the radiated power from object B is,

PB=σAeBTB4 (II)

  • PB is the power radiated by the object B
  • eB is the emissivity of the object B
  • TB is the temperature of the object B

Divide (II) by (I)

(b)

To determine
The ratio TB/TA of the temperatures.
