Q

If the pitch of the propeller is 26.7 feet, and the revolutions per day are 131,717, calculate the day's run allowing 4% negative slip.

🔍 Key Concepts

• Propeller pitch as theoretical distance traveled per revolution • How to apply negative slip percentage to reduce theoretical distance • Converting total distance in feet per day to nautical miles (use 1 nautical mile = 6,076 feet)

💭 Think About

• First, find how many feet the ship would travel in one day with zero slip. Which two numbers do you multiply? • Next, apply the 4% negative slip: does that mean you use 96% or 104% of the theoretical distance? Why? • After adjusting for slip, convert your total distance in feet to nautical miles. Which conversion factor should you use, and how do you compare your result to the answer choices?

✅ Before You Answer

• Be sure you multiply pitch × revolutions per day before applying slip • Confirm that 4% negative slip means the ship actually travels more than the theoretical pitch distance • Double-check your final step: divide total feet by 6,076 ft per nautical mile before comparing with the options
