Which of the following is an advantage of hydrogen cooling ?
Correct answer: E. All of the above
- A. Increase in efficiency
- B. Increase in ratings
- C. Increase in life
- D. Smaller size of coolers
- E. All of the above
Explanation
Hydrogen cooling reduces windage loss, improves heat transfer and permits a more compact cooler, thereby increasing efficiency and rating; it also helps reduce thermal ageing and extend machine life. Thus all the listed effects are recognized advantages.
