Q

If the pitch of the propeller is 24.8 feet, and the revolutions per day are 93,373, calculate the day's run allowing 11% positive slip.

🔍 Key Concepts

• Propeller pitch as the theoretical distance advanced in one revolution • How to convert feet per day to nautical miles or statute miles per day • Meaning of positive slip and how it affects the theoretical distance run

💭 Think About

• First, what is the ship’s theoretical distance in one day with zero slip using the given pitch and revolutions? • How do you adjust that theoretical distance when you are told there is 11% positive slip? Does the actual distance become greater or less than the theoretical distance? • Once you have the corrected distance in feet per day, how do you convert it into miles per day to compare with the answer choices?

✅ Before You Answer

• Be sure you multiply pitch × revolutions per day before applying slip. • Confirm whether you are using statute miles (5280 ft) or nautical miles (6076 ft); check which gives one of the choices. • Apply the 11% slip to the theoretical distance (not to the pitch or RPM separately).
