Which defines the pitch of a propeller on a merchant vessel?

🔍 Key Concepts

• Propeller pitch as a design measurement, not a pressure or angle • Relationship between pitch and how far the propeller would move in one revolution in ideal (no slip) conditions • Difference between pitch (distance) and blade angle (geometry/angle)

💭 Think About

• Ask yourself: Is pitch describing a distance the propeller travels per revolution, or an angle/pressure effect? • Which choice sounds like a designer’s specification you could write on a drawing: a length, an angle to the water surface, or a pressure? • Think about the term "without slip" – how is that usually defined in relation to propeller pitch in textbooks?

✅ Before You Answer

• Eliminate any option that talks mainly about pressure forces, since that’s thrust, not pitch • Separate choices that describe an angle from the one that describes a linear distance per revolution • Confirm that "without slip" refers to the theoretical advance in still water, not actual performance under load

Question 1 of 27070

Which defines the pitch of a propeller on a merchant vessel?

The positive pressure resulting from the difference of the forces on both sides of the moving propeller in still water without slip

The angle that the propeller makes with a free stream of water

The angle that the propeller makes with the surface of the water

The number of feet per revolution the propeller is designed to advance in still water without slip
