The diagram shows the cross section of a lake. Find the pressure at the bottom of the lake in unit of “metre of water”. (Assume that the atmospheric pressure is equal to 10 metre of water.)
The diagram shows the cross section of a lake. Find the pressure at the bottom of the lake in unit of Pascal. (Density of water = 1000kg/m3; Atmospheric pressure = 100,000Pa.)
The height of mercury in a barometer is 76 cmHg. If the mercury is replaced by water, find the height of the water column under the same pressure.
(Density of water = 1000 kg/m3; Density of mercury = 13,600 kg/m3)
What is the height of the mercury column in the barometer, h, as in [Density of water = 1000kg/m3; Density of mercury = 13,600 kg/m3; atmospheric pressure = 76 cmHg]
