If the pitch of the propeller is 23.2 feet, and the revolutions per day are 94,910, calculate the day's run allowing 11% negative slip.
• Propeller pitch as theoretical distance advanced in one revolution • How to apply negative slip percentage to reduce the theoretical distance • Converting total distance in feet per day to statute miles (1 mile = 5280 feet)
• First, if the propeller advanced its full pitch every revolution with 0% slip, what total distance in feet would it travel in one day? • How do you adjust that total distance when there is 11% negative slip? Are you increasing or decreasing the theoretical distance? • After finding the corrected distance in feet per day, how do you convert that value into miles and compare it with the choices?
• Be sure you are using feet for pitch and keeping units consistent before converting to miles • Double-check whether negative slip means more or less distance than the theoretical no-slip distance • Confirm your final answer is in statute miles, not nautical miles, before matching one of the options
