If the atmospheric pressure is 76 cm of Hg at what depth of water the pressure will becomes 2 atmospheres nearly.

A faulty barometer tube is 90cm long and its contains some air above mercury. The reading is cm when the true atmospheric pressure 76cm . What will be the true atmospheric pressure if the reading on this barometer is 74 cm? (H = 10cm of water column)

the height of mercury in a fauilty barometer is 75 cm and the tube above mercury is 10 cm long. The correct barometer reading is 76 cm. when the faulty barometer reads 74 cm, find the true barometer reading .

A faulty barometer contains certains amount of air and saturated water vapour . It reads 74.0cm when the atmospheric pressure is 76.0cm of mercury and reads 72.10cm when the atmospheric pressure at the air temperature=1.0cm of mercury. Find the length of the baromerer tube above the mercury level in the reservoir.

When water is used as barometer liquid the height of the water column at sea level is 76 cm.

What will be the length of mercury column in a barometer tube, when the atmospheric pressure is 76 cm of mercury and the tube is inclined at an angle of 30 ^(@) with the horizontal direction ?

If water be used to construct a barometer, what would be the height of water column at a standard atmospheric presure (76cm of mercury)?

If the length of the mercury column in a mercury barometer is 76 cm, what is the equivalent height of the water column ?
