# Water flows through a horizontal pipe that branches into two identical pipes, each with cross-sectional area equal to \( \tfrac{1}{2} \) the cross-sectional area of the original pipe. How does the speed of the water in one of the smaller pipes compare to the speed in the original pipe?

Water flows through a horizontal pipe that branches into two identical pipes, each with cross-sectional area equal to \( \tfrac{1}{2} \) the cross-sectional area of the original pipe. How does the speed of the water in one of the smaller pipes compare to the speed in the original pipe?

- **A.** The speed is \( 4 \) times greater in the smaller pipes.
- **B.** The speed is \( \tfrac{1}{2} \) of that in the original pipe.
- **C.** The speed is \( 2 \) times greater in the smaller pipes.
- **D.** The speed is the same as in the original pipe.
