Text Appearing Before Image:
edthat the second term depends only on the first power of thespeed. Since previous formulas have shown that the third termcontaining a factor of the first or second power of the speeddoes not give correct results for both low and high speeds,Mr.Blood has concluded that some intermediate value of the exponentshould be used. Mr. Blood logically concluded that,in as muchas the head and stem resistance,which comprises the greaterpart of the air resistance,does not depend on the weight of thetrain; in order to get the train resistance in pounds per ton,a weight factor should appear in the denominator of the lastterm of the equation. The equation which he considers to repre-sent actual operating conditions follows; R - 4 + 0.15 M + —M*. where R is the train resistance in pounds per ton. U is the speed of the train in miles per hour. T is the weight of the train in short tons.This formula seems to give fairly accurate results over a widerrange of conditions than any other so far published.
