Rainwater draining from a neighborhood street initially travels at 4 ft/s through a pipe with a cross-sectional area of 15.7 ft2. This pipe connects down the street to another pipe with a cross-sectional area of 65.4 ft2. What would be the speed of the water as it moves through this larger pipe?

The  velocity  is

Explanation:

From the question we are told that

   The initial speed is  

   The  cross -sectional area of the first pipe is  

   The  cross -sectional area of the second pipe is

Generally from continuity equation we have that

So
