Question
What is manometer?
Solution
Manometer is a U-tube open at both the ends having some mercury in it.
It is used to measure the gauge pressure or pressure difference of gases on the two sides of manometer tube by measuring the height difference of mercury column in two limbs of manometer tube.
If, the difference in the height column of mercury in the two limbs of tube = h, then
Gauge pressure = ρgh
Absolute pressure = Pa + ρgh.
