Extracted text: Underground water is pumped through a 10,ab (cm) diameter pipe that consists of a 2,ab (m) long vertical and 1,ab (m) long horizontal section, as shown in Fig. Water discharges to atmospheric air at an average velocity of 3 m/s, and the mass of the horizontal pipe section when filled with water is 12 kg per meter length. The pipe is anchored on the ground by a concrete base. a. Determine the bending moment acting at the base of the pipe (point A) and b. the required length of the horizontal section that would make the moment at point A zero. 1,ab (m) 3 m/s 10,ab (cm) 2,ab m
