What is pitch?

What is pitch?

• A. The distance a propeller will travel through water in one revolution.
• B. The distance a propeller will travel through a gelatinous object in one revolution.
• C. The angle between the propeller blade and the plane of rotation
• D. The thrust produced by the propeller

Answer: (B)

Pitch is the distance a propeller would move forward in one full turn if it were moving through a uniform medium, like water. It’s a measure of the forward advance per revolution, determined by the blade geometry and how the propeller is pitched. It’s not about the blade angle itself or the thrust produced. So pitch describes how far the vessel would travel per revolution, not how hard the propeller pushes or the angle of the blades.
