If the mercury barometer contains water instead of mercury, what is the height of the water column in the pipe when the external atmospheric pressure is 101,000 Pa If the mercury barometer is filled with water instead of mercury, what is the height of the water column in the pipe when the external atmospheric pressure is 101,000 Pa

P=ρgh
ρWater =1000 kg/m3
G =9.8 m/s squared
So
H=101000÷9.8÷1000=10.3m

15. When the atmospheric pressure is low in summer, the professional fish farmers need to add oxygen to the fish pond to prevent the death of fish from hypoxia. Xiao Ming designed an automatic oxygenation system. He modified the mercury barometer in the laboratory.
