Heat Balance of a Sheep in the Sun. Physical Processes in Terrestrial and Aquatic Ecosystems, Transport Processes.
Hatheway, W. H.
These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. Specifically, this module develops a method for calculating the exchange of heat between an animal and its physical environment. The approach used is to develop a mathematical model that represents the energy balance of an animal, to discuss the components of the model, and to apply these theories by working out the details of the energy budget of a familiar animal. Examples are used to illustrate that if the sheep's environment is given in terms of temperature, wind speed, and incoming radiation, it is possible to determine the rates of body metabolism and evaporative losses that will allow the animal to maintain thermal equilibrium. The model which is developed can be applied to other animals and environments and can be used to evaluate household fuel bills. A knowledge of differential equations is a prerequisite to the course.
