You are turning 88 RPM, with a propeller pitch of 19 feet, and an estimated slip of 0%. What is the speed of advance?

Correct Answer: Option D — 16.5 knots

Speed of advance is determined by the formula: Speed = (RPM * Pitch * 60) / 6080. With 88 RPM and 19 feet pitch, the theoretical speed is (88 * 19 * 60) / 6080. At 0% slip, the speed of advance is 16.5 knots, consistent with Bowditch navigation principles for propeller efficiency.
