Question 1. A I m diameter pipe bend shown in the diagram is carrying crude oil ( S.G.=0.94 ) with
a steady flow rate of 2 m'/s. The bend has an angle of 30° and lies in a horizontal plane. The volume
of oil in the bend is 1.2 m', and the empty weight of the bend is 4 kN. Assume the pressure along the
centerline of bend is constant with a value of 75 kPa gage. Find the net force required to hold the
bend in place.? (100 PTS.)
