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                        

In free con-vection heat transfer, Nusselt number is function of                        

In heat transfer, conductance equals conductivity (kcal/hr/sqm/°C/cm) divided by                        

In re generator type heat exchanger, heat transfer takes place by                        

Joule sec is the unit of                        

LMTD in case of counter flow heat exchanger as compared-to parallel flow heat exchanger is
