Heat and Mass Transfer In heat transfer, conductance equals conductivity (kcal/hr/sq.m/°C/cm) divided by K.cal (heat) Hr (time) Sq. m (area) °C (temperature) K.cal (heat) Hr (time) Sq. m (area) °C (temperature) 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, The better insulation must be put inside 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 outside The better insulation must be put inside 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 outside ANSWER DOWNLOAD EXAMIANS APP

Heat and Mass Transfer In convection heat transfer from hot flue gases to water tube, even though flow may be turbulent, a laminar flow region (boundary layer of film) exists close to the tube. The heat transfer through this film takes place by Radiation Both convection and conduction Conduction Convection Radiation Both convection and conduction Conduction Convection ANSWER DOWNLOAD EXAMIANS APP
