Question

A tank 5 m high is half filled with water and then is
filled to the top with oil of density 0.85 g/cm2. The
pressure at the bottom of the tank, due to these
liquids is​

Answer 1

pressure at bottom of the tank = dgh+Po

d=density of liquid

g=9.8m/s²

h=length of the column of liquid

Po=atmospheric pressure

P=850*2.5*9.8 + 1.013*10^5

P=20825+1.013*10^5

P=1.29*10^5 N/m²
