Abstract

In this paper we select a set of parameters to analyst the warming and cooling progress of the water in the bathtub and view the moment of adding hot water as the main standard for our evaluation. Based on Law of conservation of energy and Newton's law of cooling, the temperature model was established. The loss heat of water which is due to the heat exchange between water and air is the key. We derive a differential equation for it. Then, we find that adding hot water at 115s per cycle will lead to the least water wasting which is about 249kg. The result states that adding water too early or too late is not a sensible choice. The outcome of sensitive analyst about the flow rate displays that the effect of it on the model is small.
