In U tube manometer, what is the specific gravity of liquid whose pressure is to be measured in respect of liquid in the manometer?
1
Specific gravity of liquid in the manometer is higher in comparison to specific gravity of liquid whose pressure is to be measured
2
Specific gravity of liquid in the manometer is lower in comparison to specific gravity of liquid whose pressure is to be measured
3
There should be no difference of specific gravity
4
None of the above
