A large pump supplies 0.585 cumecs at 620KPa downward into a 75 (degree) steel bend that expands from 300mm into a 450mm horizontal pipeline lain in hard clay soil. The 75 (degree) bend is contained within a vertical plane, and the elevation difference between the inlet and outlet of the bend is 0.685m. When the bend is full of water, their combined mass is 114kg.
Calculate the area of thrust block necessary to bear the force from this pipe bend.
