A faulty barometer contains some amount of air and the saturated water vapour. It reads 74 cm when the atmospheric pressure is 76 cm if Hg and reads 72.10cm when the atmospheric pressure is 74cm. Saturation vapour pressure is 1cm of Hg at the air temperature. Find the length of the barometer tube above the mercury level in the reservoir. Kindly explain the solution so that i may understand the concept of the question!!!!!!!!!!!
