Heat and Mass Transfer Conduction is a process of heat transfer 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 without the actual motion of the particles From one particle of the body to another by the actual motion of the heated particles None of these 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 without the actual motion of the particles From one particle of the body to another by the actual motion of the heated particles None of these ANSWER DOWNLOAD EXAMIANS APP
Heat and Mass Transfer According to Dalton's law of partial pressures, (where pb = Barometric pressure, pa = Partial pressure of dry air, and pv = Partial pressure of water vapour) Pb = pa + pv Pb = pa/pv Pb = pa × pv Pb = pa - pv Pb = pa + pv Pb = pa/pv Pb = pa × pv Pb = pa - pv ANSWER DOWNLOAD EXAMIANS APP
