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
