Shortest distance between two tubes is___________________?
Correct answer: B. Called tube clearance
- A. Called tube pitch
- B. Called tube clearance
- C. More in case of triangular pitch as compared to square pitch of tube layout
- D. None of these
Explanation
Tube clearance is the shortest gap between the outside surfaces of adjacent tubes, whereas tube pitch is measured from the centre of one tube to the centre of the next. Thus, the shortest distance is called tube clearance.
