Fluid runs through a drainage pipe with a 10-cm radius and a length of 30m (3000 cm). The velocity of the fluid gradually decreases from the center of the pipe toward the edges as a result of friction with the walls of the pipe. For the data shown, v(x) is the velocity of the fluid (in cm/sec) and x represents the distance (in cm) from the center of the pipe toward the edge. 3 4 v(x) 195.6 195.2 194.2 193.0 191.5 У(х) 189.8 188.0 185.5 183.0 180.0 a.
