You are turning 84 RPM, with a propeller pitch of 22 feet, and an estimated slip of 0%. What is the speed of advance?

Correct Answer: Option C — 18.2 knots

Determine speed of advance via the formula: Speed = (RPM * Pitch * 60) / 6080. With 84 RPM and 22 feet pitch, the calculation (84 * 22 * 60) / 6080 results in 18.2 knots. This calculation assumes 0% slip, representing the ideal distance the propeller moves through the water per hour.
