Heat Transfer from Steam to Water Lab Report Example | Topics and Well Written Essays - 3000 words - 1

Heat Transfer from Steam to Water - Lab Report Example Heat is a form of energy and the level of energy contained in a certain object is shown by the level of temperature in the object. The main purpose of this experiment was to test on the heat transfer from steam to water. Stem is usually produced when the water is heated to its boiling point and the heat can also be transferred from steam to water. Unlike the heat transfer by the other processes, e.g. condensation, radiation and conduction, heat transfer by condensation for example in steam does not involve temperature change. The steam passes on its latent heat to the products when it condenses on the heat transfer surface. This product formed for the condensate still contains its own sensible heat and this heat is of the same temperature that is contained in the steam from which it was produced. This experiment uses two sets of equipment. The first set is described under â€Å"Heating Liquids in Tank Storage.† The second set is described under â€Å"Corning Heat Exchanger.â €  The main aim of this experiment is to test on the heat transfer from the steam to water and to produce analysis from the data collected in the lab. Usually, the latent heat that is contained within the steam is released instantly as the steam condenses into the liquid state. The amount of latent heat that is released ranges from 2-5 times greater than the amount of sensible heat available from water after cooling.The objective is to determine the overall heat transfer coefficient (Uo) for the external heat exchanger at two different water circulation rates.   The rate of heat transfer that is often obtained during the condensation of the vapour is always very crucial since it is used in many industries in the steam heated vessels where the steam condenses and produces the heat. It is also applied in the distillation and evaporation where vapors produced must first be condensed. The latent heat of vaporization is produced at a constant temperature that is the boiling temperat ure of the liquid. The Equations were used to compute the over-heat transfer coefficient. The equations enabled the valves of both experimental as well as heat transfer coefficient to be calculated.
