Question

A closed tank contains 0.5  {m} thick layer of mercury (specific gravity =13.6 ) at the bottom. A 2.0  {m} thick layer of water lies above the mercury layer. A 3.0  {m} thick layer of oil (specific gravity =0.6 ) lies above the water layer. The space above the oil layer contains air under pressure. The gauge pressure at the bottom of the tank is 196.2  {kN}{/}{m}^{2}. The density of water is 1000  {kg}{/}  {m}^{3} and the acceleration due to gravity is 9.81  {m} {/}  {s}^{2}. The value of pressure in the air space is
