Q

You are turning 93 RPM, with a propeller pitch of 25 feet, and an estimated slip of 0%. What is the speed of advance?

🔍 Key Concepts

• Speed of advance (SOA) using propeller RPM and pitch • Unit conversions between feet per minute and knots • Relationship: Speed = Pitch × RPM (when slip is 0%)

💭 Think About

• How many feet does the propeller theoretically advance in one minute at 93 RPM with 25 ft of pitch? • Once you have feet per minute, how do you convert that to knots (nautical miles per hour)? • What constant do you use to convert feet per second or feet per minute into knots?

✅ Before You Answer

• Be sure to convert minutes to hours correctly when going from RPM to speed in knots. • Confirm that 1 nautical mile = 6076 feet (or 6076.1 ft, depending on convention used in your course). • Double-check that you kept track of whether you were working in feet per minute or feet per second before converting to knots.
