Water flows through a rectangular pipe at a speed of 3.73 m/s. The cross-sectional area of the pipe has a width W = 1.84 cm and a length L = 25.0 cm. The pipe then runs through a connection that changes the cross sectional area of the pipe to a circle. If the speed of water in the circular pipe is now 20.0 m/s, what is the radius R of the new pipe? Give your answer in cm. Note: ignore...
