www.ijaiem.orgFor free convection heat transfer, the physical properties of air are calculated at mean film temperature (average of tube temperature and surrounding temperature)[5]. The average Nusselt number has been calculated by: Where d is the outer diameter for tube (m), K represent the thermal conductivity of air at .
