A 3-cm-diameter horizontal pipe attached to a surface makes a 90° turn to a vertical upward direction before the water is discharged at a velocity of 6 m/s. The horizontal section is 5 m long and the vertical section is 4 m long. Neglecting the mass of the pipe and considering the weight of the water contained in the pipe, the bending moment acting on the base of the pipe on the wall is

(a) 11.9 N·m 

(b) 46.7 N·m 

(c) 127 N·m

(d) 104 N·m 

(e) 74.8 N·m
