Abstract : This report analyzes a number of balloon flights to determine empirical constants for the equation developed by the University of Minnesota. A computer program RISERATE was developed to accept flight data for the values in the percent lift equation shown and solve simultaneous equations for values of the empirical constants C1 and C2. These average values for balloons up to 20 million cubic feet volume were C1 = 0.000378 and C2 = 0.000000463. (Modified author abstract)
