If the pitch of the propeller is 20.6 feet, and the revolutions per day are 107,341, calculate the day's run allowing 3% positive slip.

Correct Answer: Option D — 352.7 miles

Calculate the theoretical distance by multiplying the pitch by the total revolutions. Apply the 3% positive slip by multiplying the theoretical distance by (1 - 0.03). This accounts for the efficiency loss of the propeller in the water, resulting in a total day's run of 352.7 miles.
