What is the difference in
pressure between the top and bottom of a vessel 76 cm deep at `27^(@)C` when filled with
(i) water
(ii) mercury ?
Density of water at `27^(@)C` is 0.990 g `0.990" g" cm^(-3)` and that of mercury is `13.60" g cm"^(-3)`.

Text Solution

Pressure `="height"xx"density"xx"g"`
Case (i). Pressure difference`=76" cm" xx0.99" g"cm^(3)xx981" cm"//s^(2)`
`=7.38xx10^(4)" dynes" cm^(-2)=0.73" atm" (1" atm"=1.013xx10^(6)" dynes "cm^(-2))`
Case (ii). Pressure difference `=76 cmxx13.6" g"//cm^(3)xx981" cm"//s^(2)=1.013xx10^(6)" dynes" cm^(-2)=1" atm"`.

Suppose water is used in a barometer instead of mercury. If the barometric pressure is 760 mm Hg , what is the height of the water column in the barometer at 0^(@) C . The densities of water and mercury at 0^(@) C are 0.99987 g cm^(-3) and 13.596 g cm^(-3) , respectively. Strategy : The prtessure exerted by a column of liquid h whose density is d is hdg . Because the pressure are equal , we can equate the expressions for water (W) and mercury (M): h_(W)d_(W)g = h_(M) d_(M)g or h_(W)d_(W) = h_(M)d_(M) Rearranging gives (h_(W))/(h_(M)) = (d_(M))/(d_(W)) This implies that the height of the liquid column in inversely proportional to its density . Solve the equation to find the height of the water column, h_(W) .
