Consider that water (ρ_water
= 1.0 g/cm³) is flowing through a pipe with diameter D1 = 3.0 cm, as shown below. The speed of the water in relation to this tube is given by vz = (8-r²) (cm/s). Determine the average speed of the water (in cm/s) that passes through the pipe with diameter D2 = 0.6 cm. Consider the flow to be permanent, incompressible, and one-dimensional.
