The Natural convective heat transfer rate in isothermal narrow plates are experimentally and numerically studied. In a 3-dimensional model if one dimension compared, less than other dimensions then heat transfer rate is read high in value and this can be calculated by experimentation two-dimensional flow analysis. The fluid properties are assumed constant, the change of density with the temperature generates buoyancy forces. Experimental natural convection heat transfer analysis is conducted on narrow plates placing in various positions to know its effect on convection and their particular co-efficient of heat transfer are known. Dimension less numbers such as Grashof's Number and Prandtl Number are vital in calculations. This experimentation helped in the study of convection of three different substances and their importance to be used in particular applications. The experimentation briefed the convection rate and concluded that Copper has high convection rate and Aluminium shows high convection rate when the dimensional thickness of Aluminium is half that of copper. Experiments showed that Aluminium can be cheaper substitute of copper in various applications. Analysis is done to know the heat flow pattern inside the solid.++
