70% to passIf the pitch of the propeller is 25.1 feet, and the revolutions per day are 91,591, calculate the day's run allowing 7% positive slip.
A
351.6 miles
B
390.0 miles
C
378.1 miles
D
404.6 miles
AI Explanation
The correct answer is A) 351.6 miles. To calculate the day's run, we need to use the formula: Day's run = Propeller pitch x RPD x (1 - Slip), where RPD is the revolutions per day and Slip is the positive slip percentage. Given information: - Propeller pitch = 25.1 feet - Revolutions per day (RPD) = 91,591 - Positive slip = 7% Plugging in the values: Day's run = 25.1 feet x 91,591 x (1 - 0.07) Day's run = 25.1 feet x 91,591 x 0.93 Day's run = 2,131.7 feet Day's run = 351.6 miles The other options are incorrect because they do not accurately reflect the calculation using the given information and the formula for day's run.
