The pipes connected to the closed tank are completely filled with water (at 10°C). If the absolute pressure at A is 280 kPa, determine the absolute force (in N) acting

on the inside of the end cap at B.The pipes have an inner diameter of 60 mm. The dimensions are xo = 1 m, to=1.1 m, zo = 0.75 m and zc= 0.5 m.
