Change of the Warm Water Temperature for the Development of Smart Healthecare Bathing System

摘要

In this study,heat loss through free surface of water contained in bathtub due to conduction and evaporation has been analyzed.As a result of this study,a relational equation has been derived based on the basic theory of heat transfer to evaluate the performance of bath tubes.The derived equation was rational and quantitative.The major heat loss was found to be due to evaporation.Moreover,it has been found out that the speed of heat loss depends more on the humidity of the bathroom than the temperature of water contained in the bathtub.So,it is best to maintain the temperature of bathtub water to be between 41 to 45 deg C and the humidity of bathroom to be 95%.
