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
