Question
A tall tank filled with water has an irregular shape as shown. The wall CD makes an angle of 45^{0} 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 P_{1}, P_{2} and P_{3} 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,
