Question

At a given place a barome
sa pressure of 70 cm of mercury. If the mercury in the
barometer is replaced by
w water, then the height of the water column
Take density of mercury = 13600 kg/m3 dens
kg/mº, density of water = 1000 kg /m)
​

Answer 1

Answer:

9.52 metres or 952 cm

Explanation:

Since both of them are at the same given place, both of them will read the same atmospheric pressure so pressure readings in both will be the same.

=> P1 = P2

=> p1h1g = p2h2g

=> p1h1 = p2h2

=> h2 = p1h1/p2

=> h2 = 13600 x 0.7 / 1000. ( 70 cm = 0.7m)

=> h2 = 9.52 m

Hence, height of the water column will be 9.52 metres at the same given place.
