Due to the large number of parameters required for the accuracy of the model, which may not be available in some cases, the values \u00a0calculated\u00a0 by the model have been compared \u00a0with the values resulting from experimental equations that need less number of \u00a0inputs, the two experimental equations (Hargreaves and Evanov) were adopted.
