Question 91Navigation Problems
70% to passYou are turning 105 RPM, with a propeller pitch of 17 feet, and an estimated slip of -1%. What is the speed of advance?
A
17.8 knots
B
15.3 knots
C
16.9 knots
D
17.4 knots
AI Explanation
The correct answer is A) 17.8 knots. To calculate the speed of advance, we can use the formula: Speed of Advance = RPM x Propeller Pitch x (1 - Slip/100). Given the information provided - 105 RPM, 17 feet propeller pitch, and -1% slip - plugging these values into the formula gives us a speed of advance of 17.8 knots. The other options are incorrect because they do not accurately reflect the calculated speed of advance based on the provided parameters. The formula-based calculation clearly shows that the correct answer is 17.8 knots.
