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, The better insulation must be put outside The better insulation must be put inside One could place either insulation on either side One should take into account the steam temperature before deciding as to which insulation is put where The better insulation must be put outside The better insulation must be put inside One could place either insulation on either side One should take into account the steam temperature before deciding as to which insulation is put where ANSWER DOWNLOAD EXAMIANS APP
Heat and Mass Transfer Two balls of same material and finish have their diameters in the ratio of 2: 1 and both are heated to same temperature and allowed to cool by radiation. Rate of cooling by big ball as compared to smaller one will be in the ratio of 0.042361111111111 0.084027777777778 0.043055555555556 0.16736111111111 0.042361111111111 0.084027777777778 0.043055555555556 0.16736111111111 ANSWER DOWNLOAD EXAMIANS APP
