An open topped tank with a base area of 1m2
contains a layer of water 0:5m deep below an
oil layer 1m deep. If the densities of water and oil are 1000kg=m3
and 850kg=m3
respectively,
determine:
(a) the pressure 0:5m below the free surface
(b) the pressure at the tank base
(c) the force on the base by the ?uid
(d) the weight of the oil
(e) the weight of the water
(f) the total weight of ?uid
