Question

At a given place mercury barometer record a pressure of 0.70 of hd what would be the height of water column is mercury in barometers is replaced by fortis take density of mercury to be 13.6 into 10 to the power 3

Answer 1

Answer:

Hi..

Explanation:

Height of mercury in barometer : 0.70 m

If water is replaced by mercury then resulting reading : ?

Density of hg : 13600 kg/m^3

Density of water :1000kg /m^3

Height of water in barometer if replaced by mercury is

=>height of water =density of hg /density of water multiplied by height of mercury

=>h=13600/1000 x 0.70 => 13.6 x 0.70

= 9.52m

Therefore, the height of water when displaced by mercury is 9.52 m
