1. The problem statement, all variables and given/known data Water flowing through a 2.68 cm diameter pipe fill a 284 L bathtub in 8.2 minutes. What is the speed of the water in the pipe? 2. Relevant equations p+pgh +1/2pv^2=p2 +pgh + 1/2pv2^2 3. The attempt at a solution I know that p=pat for both cases but the water does not start from any height and does not end up at any height. I don't know how to start that one. Thank you for your help.
