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 Depending on the radiating properties, a body will be white when(Where a = absorptivity, p = reflectivity, x = transmissivity) P = 0, x = 1 and a = 0 P=1, T = 0 and a = 0 P = 0, x = 0 and a = 1 X = 0, a + p = 1 P = 0, x = 1 and a = 0 P=1, T = 0 and a = 0 P = 0, x = 0 and a = 1 X = 0, a + p = 1 ANSWER DOWNLOAD EXAMIANS APP
