1. The problem statement, all variables and given/known data Water runs into a fountain, filling all the pipes, at a steady rate of 7.52×10−2 m^3/s How fast will it shoot out of a hole 4.53cm in diameter? 2. Relevant equations A1V1 = A2V2 3. The attempt at a solution A1V1 = 7.52x10-2 m^3/s = A2V2 Divide by A2, which would be 4.53/2 (to get Radius) = 2.265 --> .02265m or 2.265x10-2 Now, for A2, am I suppose to square it to get m/s as my answer? I'm assuming so since V1=m/s so that must mean A1 = m^2. If I do all of that, I get (7.52x10-2 m^3/s) / (2.265x10-2 m)^2 = 146 m/s which I think is wrong. Thanks for the help.
