A pitched-blade turbine draws ______________ a straight blade turbine?
Correct answer: A. Less power than
- A. Less power than
- B. More power than
- C. Same power as
- D. Data insufficient to predict
Explanation
A pitched-blade turbine generally has a lower power number than a straight-blade turbine of comparable size and speed, so it consumes less power. Its inclined blades promote axial circulation rather than the stronger radial pumping of straight blades.
