The figure shows two sections of an old pipe system that runs through a hill, with distances
dA = dB = 31.0 m and D = 105 m. On each side of the hill, the pipe radius is 2.30 cm. However,
the radius of the pipe inside the hill is no longer known.To determine it, hydraulic engineers
first establish that water flows through the left and right sections at 2.10 m/s. Then they
release a dye in the water at point A and find that it takes 92.0 s to reach point B. What is the
average radius of the pipe within the hill?
