🔍 Key Concepts

• Propeller pitch as theoretical advance per revolution (convert feet and inches to decimal feet) • Effect of slip percentage, including a negative slip value, on actual advance per revolution • Using RPM over 24 hours to find total distance, then converting feet to nautical miles/statute miles as appropriate

💭 Think About

• First, find how many feet your vessel would theoretically advance in one revolution from the given pitch, and then adjust that number for the -3% slip. How does a negative slip change the theoretical advance? • Next, compute how many revolutions the propeller makes in a full day at 82 RPM. How many minutes are in a day, and how do you relate RPM to total revolutions? • Finally, multiply distance per revolution by total revolutions to get total distance in feet. Then convert that distance into miles and compare with the answer choices.

✅ Before You Answer

• Be sure you convert 19'09" correctly into decimal feet before using it in any formula. • Confirm you are using a 24-hour period for the "day's run" when calculating total revolutions. • Check that you are converting from feet to miles with the correct unit (statute vs. nautical) that matches the scale of the answer choices.
