1. The problem statement, all variables and given/known data Water is flowing at 1 m/s in a circular pipe. If the diameter of the pipe decreases to four-ninth its former value, what is the velocity fo the water downstream? 2. Relevant equations AV=AV 3. The attempt at a solution[/b (Area1)(Velocity1)=(Area2)(Velocity2) then... (A1)(1 m/s)=(4/9)A1(V2) ? or A1=(4/9)(V2) Is that right what would u do next??
