Abstract
A method and algorithm for predicting the fluid loss rate of a system, uses data for the leak rate from the system for a substitute fluid that leaks at a different rate than the system fluid. In the illustrated embodiment, the system is a pneumatic tire and the substitute fluid is helium gas. The helium leak rate data is used in a Fortran program to predict the air loss rate from the tire by determining the leak rate factor f' for helium, as compared to air, and using 'f' to calculate the air loss rate.
