70% to passIf the pitch of the propeller is 21.5 feet, and the revolutions per day are 96,666, calculate the day's run allowing 9% negative slip.
A
341.8 miles
B
372.6 miles
C
357.9 miles
D
311.1 miles
AI Explanation
The correct answer is B) 372.6 miles. The formula to calculate the day's run is: Day's Run = (Pitch x RPD x (1 - Slip %)) / 5,280, where Pitch is the propeller pitch in feet, RPD is the revolutions per day, and Slip % is the negative slip percentage. Given the information provided: Pitch = 21.5 feet RPD = 96,666 Slip % = 9% Plugging these values into the formula: Day's Run = (21.5 x 96,666 x (1 - 0.09)) / 5,280 = 372.6 miles The other options are incorrect because they do not accurately apply the formula using the provided information.
