1. A garden hose has an internal diameter of 1.5cm. It's connected to a sprinkler that consists merely of an enclosure with 14 holes, each .20 cm in diameter. The water in the hose moves with a speed of 3.0m/s. At what speed does the water leave the sprinkler? OK, so some relevant equations I think would be area- 1/2*pi*r^2. Where i go from there i'm not sure. I also know that the water should leave at a faster speed since it is being forced through many smaller holes. Your thoughts?
