Fortin barometer

160cc water in a container area 25 sqcm => height 6.4 cm


going to MKS units

to find the "cm of mercury equivalent" to the pressure of6.4cm of water.


rho-waterxgxh = 1000x9.81x6.4x10^-2

rho-mercury = 13,600x9.81xh-mercury


13,600x9.81xh-mercury=h = 1000x9.81x6.4x10^-2

h-mercury = 1000x9.81x6.4x10^-2/ 13,600x9.81

=>0.004 metres.

=>0.4cm

=>76.4cm

=> C
