A vat contains a mixture of oil and water. The water forms a lower layer which is 0.8 m deep, and above it there is an oil layer 0.3 m thick. The
density of water is 1000 kg/m³, and the density of oil is 800 kg/m3.
Find the force on a flat door at the bottom of the vessel that has a cross-sectional area of 0.5 m2.
The acceleration due to gravity is 9.81 m/s2.
Oil, P. = 800 kg/m3
h. = 0.3 m
