🔍 Key Concepts

• Propeller pitch as the theoretical distance advanced per revolution • How to convert feet per day to nautical miles per day (day's run) • Effect of negative slip on the theoretical distance traveled

💭 Think About

• First, ignore slip and find how many feet the vessel would advance in one day based only on pitch and revolutions. What operation combines pitch and revolutions? • Next, apply 9% negative slip. Does negative slip mean the vessel travels more or less than the theoretical distance? By what factor should you adjust? • Finally, convert your adjusted distance in feet to nautical miles. What is the standard number of feet in one nautical mile?

✅ Before You Answer

• Be sure you use revolutions per day, not per minute or per hour, when multiplying by pitch • Apply the 9% negative slip in the correct direction (greater than 100% or less than 100% of theoretical distance?) • Use 6,076 feet per nautical mile (approximate) for your final conversion and compare your result with the choices
