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

Heat and Mass Transfer Two long parallel surfaces each of emissivity 0.7 are maintained at different temperatures and accordingly have radiation heat exchange between them. It is desired to reduce 75% of the radiant heat transfer by inserting thin parallel shields of emissivity 1 on both sides. The number of shields should be Four One Two Three Four One Two Three ANSWER DOWNLOAD EXAMIANS APP
