An oil tank, 14 m diameter and 10 m high, is proposed for a site where there is an existing pipeline. Determine the change in stress at 0.5 m increment imposed by the tank on the pipeline along one-half the circumference nearest to the tank. The tank's empty weight is 350 kN. Assume the tank is filled to 90% of its capacity. Take SGoil = 0.85. [8] 1 m 3 m 2m E T 4 m 0.5 m O Q. I. b Water tank
