Heat and Mass Transfer In regenerator type heat exchanger, heat transfer takes place by Direct mixing of hot and cold fluids Generation of heat again and again Flow of hot and cold fluids alternately over a surface A complete separation between hot and cold fluids Direct mixing of hot and cold fluids Generation of heat again and again Flow of hot and cold fluids alternately over a surface A complete separation between hot and cold fluids ANSWER DOWNLOAD EXAMIANS APP
Heat and Mass Transfer The process of heat transfer from one particle of the fluid to another by the actual movement of the fluid particles caused by some mechanical means, is known as Free convection Radiation Conduction Forced convection Free convection Radiation Conduction Forced convection ANSWER DOWNLOAD EXAMIANS APP
Heat and Mass Transfer A steam pipe is to be insulated by two insulating materials put over each other. For best results Both may be put in any order Better insulation should be put over pipe and better one over it Inferior insulation should be put over pipe and better one over it Whether to put inferior OIL over pipe or the better one would depend on steam temperature Both may be put in any order Better insulation should be put over pipe and better one over it Inferior insulation should be put over pipe and better one over it Whether to put inferior OIL over pipe or the better one would depend on steam temperature ANSWER DOWNLOAD EXAMIANS APP
Heat and Mass Transfer Conduction is a process of heat transfer None of these From one particle of the body to another without the actual motion of the particles From a hot body to a cold body, in a straight line, without affecting the intervening medium From one particle of the body to another by the actual motion of the heated particles None of these From one particle of the body to another without the actual motion of the particles From a hot body to a cold body, in a straight line, without affecting the intervening medium From one particle of the body to another by the actual motion of the heated particles ANSWER DOWNLOAD EXAMIANS APP
