Modes of Heat Transfer S K Mondal’s Chapter 1 Previous 20-Years IES Questions Heat Transfer by Conduction IES-1. A copper block and an air mass block having similar dimensions are subjected to symmetrical heat transfer from one face of each block. The other face of the block will be reaching to the same temperature at a rate: [IES-2006]

HEAT AND MASS TRANSFER

Besides, heat and mass transfer must be jointly considered in some cases like evaporative cooling and ablation. The usual way to make the best of both approaches is to first consider heat transfer without mass transfer, and present at a later stage a briefing of similarities and differences between heat transfer and mass transfer,

Heat Transfer, Conduction, Convection and Radiation

Where q is the heat transferred by radiation, E is the emissivity of the system, σ is the constant of Stephan-Boltzmann (5.6697 x 10^-8 W/m^2.K^4), A is the area involved in the heat transfer by radiation, and (ΔT)^4 is the difference of temperature between two systems to the fourth or higher power.

Units of Thermal Conductivity

In SI units, thermal conductivity is measured in watts per meter-kelvin – W/(m·K).In Imperial units, thermal conductivity is measured in BTU/(hr·ft⋅°F).. Note that, British Thermal Unit (unit: BTU) is defined to be the amount of heat that must be absorbed by a 1 one pound of water to raise its temperature by 1 °F at the temperature that water has its greatest density (approximately 39 ...
