Question
A vessel that contains a gas has two pressure gauges
attached to it. One contains liquid mercury, and the other
an oil such as dibutyl phthalate. The difference in levels of
mercury in the two arms of the mercury gauge is observed
to be 9.50 cm. Given
density of mercury
13.60 g cm-3
-3
density of oil = 1.045 g cm¯
acceleration due to gravity = 9.806 m s
(a) What is the pressure of the gas?
(b) What is the difference in height of the oil in the two
arms of the oil pressure gauge?
