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 Conduction Both convection and conduction Convection Radiation Conduction Both convection and conduction Convection Radiation ANSWER DOWNLOAD EXAMIANS APP
