Table of Dollar-Cost Per Pound of Drag at Speeds from 100 to 300 mph.
This table shows the cost for one pound of aerodynamic drag at flying speeds from 100 mph to 300 mph. Propeller efficiency factor "n" = 0.80. Fuel cost = $US2.00 per US gallon. The purpose of the table is strictly for cost comparison. Although we know that fast airplanes have higher "n" factors, as the table is meant only to show the increasing cost of drag with higher speeds, the "n" factor is kept at 0.80.
