Density in CGS 13.6 g / cm3
Density in SI 13600 kg / m3
What length of water column is equivalent to 0.86 m of mercury column?
Given: density of mercury is 13.6 times the density of water.
The height of a mercury column in a barometer in a Calcutta library was recorded to be 75cm.Calculate this pressure in SI and CGS units using the following data : Specific gravity of mercury = 13.6,Density of water = 103 kg/m3,g = 9.8 m/s2 at Calcutta .Pressure = hpg in usual symbols.
