Heat Transfer - Engineering
Q1: Stefan-Boltzman law which describes the radiation heat transfer states that, it is proportional to (where, t = temperature in °C T = absolute temperature in ° K )A t4
B T4
C 1/t4
D 1/T4
ANS:B - T4 The Stefan-Boltzmann law, which describes radiation heat transfer, states that the radiative heat flux (Q) is proportional to the fourth power of the absolute temperature (T) of the radiating surface. Mathematically, it is expressed as: 4Q=σT4 Where:
