The geometric model of the equivalent of the human body

In determining of geometric parameters of bodies of complex shape, their geometric equivalents are often used in the form of bodies of regular shape having the same values of linear dimensions, volume or surface area. The aim of the study is to obtain formulas for finding the semi-axes of an equivalent cylinder in values of growth, body weight and density or volume, as well as the surface area of the human body. It is shown that the geometric equivalent of a human body is an elliptical cylinder whose height, volume and surface area are equal to the corresponding body parameters. Such a geometric equivalent can be used as a generalized human anthropometric parameter, as well as a phantom for experimental studies on human and environmental heat exchange, in evaluating the thermal insulation properties of tissues and for other experiments in applied anthropology.
