Question

In the specifications of a screw conveyor, the shaft length is shorter than the flight length.

(a) True

(b) False

I have been asked this question in an online quiz.

Origin of the question is Unit Operations topic in chapter Sedimentation and Centrifuge, Mixing, Size Reduction and Separation and Material Handling and Transportation of Food Engineering

Answer 1

Correct option is (b) False

The explanation is: In the specifications of a screw conveyor, the shaft length is more than the flight length. The shaft length covers the length of the entire shaft whereas the flight length only covers the length of the first screw (starting from one end) to the last screw.
