Abstract: This paper realise the out line of Heat transfer coefficient for circular copper tube of polished and non-polished through vapour bubbles form of filmwise or dropwise condensation and summurise the main result with its corellation application. During processes of this set up visually observe the exchange of heat during dropwise and filmwise condensation. This unit contained with an integrated steam generator boiler and steam extraction through control valve to the chamber tubes. Condensation of steam on the surface of tubes causes heat transferred from steam to tubes ,into water as heat exchange medium, at peak stage due to temperature difference may condense in to two ways-dropwise or filmwise on tube surfaces.in film -wise condensation, the heat from the vapour to the cooling medium is transferred through the film of the condensate formed on the surface ,where as in dropwise condensation process, only a part of surface is covered with condensate. Due to good contact between the vapour and surface very high heat transfer rates are reported in dropwise process. However, it has been difficult to sustain drop wise condensation commercially for long periods of time.
