Given a long glass tube closed at one end having a uniform cross-section
containing a mercury column of 10 cm length, at a distance of
30 cm from the closed end when held vertically as shown. The
air trapped above the Hg column has pressure 85 cm of Hg.
What will be the length of air column
if the glass tube is held horizontally ?

It lies horizontally, the middle 5 cm containing mercury and the two equal ends containing air at the same pressure P. When the tube is held at an angle of 60° with the vertical direction, the length of the air column above and below the mercury column are 46 cm and 44.5 cm respectively. Calculate the pressure P in centimetre of mercury. (The temperture of the system is kept at 30° C). [1986-6 marks]
