### Question

A tall tank filled with water has an irregular shape as shown. The wall CD makes an angle of 450 with the horizontal; the wall AB is normal to the base BC. The lengths AB and CD are much smaller than the height h of water (figure not to scale).

Let P1, P2 and P3 be the pressures exerted by the water on the wall AB, base BC and the wall CD respectively. Density of water is ρ and g is acceleration due to gravity. Then, approximately,
