The tube of an inclined tube manometer has its
upper end open to air and the lower end
connected to vertical cylinder trough having a
diameter 4 times that ofthe tube. The slope of
the tube is 1 in 4 and specific gravity of
manometer liquid is 0.72. The space above the
liquid in the trough is connected to a gas
chamber. When the movement of meniscus in
the tube is 8 cm, change in gas pressure, in
height of water column, is
