Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

Question

Use heat and mass transfer data book

A furnace wall emits radiation at 2000K. Treating it as black body radiation, calculate the
following. :
(i) Monochromatic radiant flux density at 1 mm wavelength.
(ii) Wavelength at which emission is maximum and the corresponding emissive power.
(ii) Total emissive power

Net movement of mass from one location, usually meaning stream, phase, fraction, or component, to another. Mass transfer occurs in many processes, such as absorption, evaporation, drying, precipitation, membrane filtration, and distillation.

A thin, disk-shaped silicon wafer of diameter D=20 cm on a production line must be maintained at a temperature of 100 deg C. The wafer loses heat to the room by convection and radiation from its upper surface, while heat is supplied at a constant flux from below. The surrounding air is at 20 deg C, while all surrounding surfaces (which can be treated as blackbodies) can be approximated to be isothermal at a temperature of 15 deg C.
