Water is flowing in a cylindrical pipe of varying circular cross-sectional area, and at all points the water completely fills the pipe. At one point in the pipe, the radius is 0.155 m. What is the speed of the water at this point if the volume flow rate in the pipe is 1.50 m^3/s .At a second point in the pipe, the water speed is 3.75 m/s. What is the radius of the pipe at this point?
