Heat and Mass Transfer Depending on the radiating properties, body will be transparent when (Where a = absorptivity, p = reflectivity, x = transmissivity) P = 0, x = 0 and a = 1 X = 0, a + p = 1 P = 0, x= 1, and a = 0 P=1, x = 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, x = 0, and a = 0 ANSWER DOWNLOAD EXAMIANS APP
Heat and Mass Transfer A steam pipe is to be lined with two layers of insulating materials of different thermal conductivities. For the minimum heat transfer, One should take into account the steam temperature before deciding as to which insulation is put where One could place either insulation on either side The better insulation must be put inside The better insulation must be put outside One should take into account the steam temperature before deciding as to which insulation is put where One could place either insulation on either side The better insulation must be put inside The better insulation must be put outside ANSWER DOWNLOAD EXAMIANS APP
