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