1. The problem statement, all variables and given/known data A 1 meter long hose of 8 cm diameter is conneted to a faucet. The end of this hose is connected to a second hose which is 4 meters long and 4 cm in diameter. At the open end of the second hose water flows out at a rate of 8 cm cubed/s. What is the ratio of the speed of the water flowing in the second hose to the speed of the water flowing in the first hose? 2. Relevant equations P = F/A Not sure what other equations I could be using! 3. The attempt at a solution At first I assumed v1/A1 = v2/A2, so (8 cm cubed/s)/(4pi) = (x)/(16pi), and thus the answer ought to be 1/4, but that is incorrect. I also tried to use squares, since I reasoned that a = (v^2)/r, but this gave me the equally incorrect ratio of 1/8. Help!
