It's density is too low so u have to take an extra large tube which is inconvenient and also water will evaporate so u have to refill it again and again

Hey
here's your answer !!
Reasons why water is not a suitable barometric liquid ----->
( a ) The density of water is low ( = 1000 kg / m^3 ) , so nearly 10.4 m height of water column is needed to balance the normal atmospheric pressure . But it is highly inconvenient to take a tube of height 10.4 m for a barometer .
( b ) Water sticks with thr glass tube and wets it , so the reading becomes inaccurate .
Hope it helps !!
