A tank 5m high is filled with water up to 3m then is filled to the top with oil of density 0.85g/cm3. The pressure at the bottom of the tank due to these liquid if the gravity is__________

Given,

Height of the tank =5m

Height of water filled=H= 2.5m

Density of water=X= 1000kg/M3

Pressure by water= HX x g

= 2.5 x 1000 x 9.81 = 24.5 KPa

Height of oil filled=h= 2.5m

Density of oil = x = 850kg/M3

Pressure by oil= hx x g

= 2.5 x 850 x 9.81 = 20.825 KPa

Hence total pressure = 24.5+20.825

=45.325KPa
