To solve the problem, we will use the principle of continuity in fluid mechanics, which states that the product of the cross-sectional area (A) and the velocity (V) of a fluid remains constant along a streamline. ### Step-by-Step Solution: 1. **Identify Given Values:** - Speed of water entering the tube (V1) = 2 m/s - Speed of water emerging from the tube (V2) = 8 m/s ...
