PURPOSE:To enable immediate determination of the density, viscosity and constant pressure specific heat of the air in any condition simply by inputting a pressure value and a temperature value. CONSTITUTION:Any condition of air is determined by the temperature and the pressure. If the function of physical property can be expressed by the temperature and the pressure, it enables the calculation of the physical property values in any condition. Therefore, when an arbitrary pressure and temperature is inputted into a calculator, a physical property value can be found corresponding to the inputs from the relationship based on a widely accepted empirical formula. |
