Share:
- 1The manometric fluid must be completely miscible with the fluid being measured.
- 2There should be no difference in specific gravity between the two fluids.
- 3The specific gravity of the manometric fluid must be lower than that of the fluid being measured.
- 4The specific gravity of the manometric fluid must be significantly higher than that of the fluid being measured.✓
Correct answer
The specific gravity of the manometric fluid must be significantly higher than that of the fluid being measured.
