Boiler draught of 10 mm water column is equivalent to_____________________?
Correct answer: B. 10 kgf/m2
- A. 1 kgf/m2
- B. 10 kgf/m2
- C. 10 kgf/mm2
- D. 1 kgf/mm2
Explanation
A water head of 1 mm corresponds approximately to 1 kgf/m², so 10 mm water column gives about 10 kgf/m². The units kgf/mm² are enormously larger and are not appropriate here.
