![Current Attempt in Progress
In the 1930s, the U.S. Navy operated dirigibles. The largest was the U.S.S. Akron with a length of 785 ft and a maximum diameter of
132 ft. Its maximum speed was 84 mph (123.2 ft/sec). Moving at top speed at 10,000 ft standard atmosphere, estimate the power
required in horsepower to overcome the friction drag. Disregard effects of fins and other protrusions. Assume the surface of the
dirigible is smooth and the friction drag is that over a flat plate. (Hint: "unwrap" the outer surface of the ship.)
