Units -- is this m/s or mm/s? 1. The problem statement, all variables and given/known data N/A 2. Relevant equations Continuity A1*v1=A2*v2 A=pi*r² 3. The attempt at a solution I've solved a problem as follows (pi * 10.0mm²)(0.200m/s)=(pi * 2.50mm²)(v2) 3.20 xx/s = v2 I am pretty sure it's in m/s, but having the radii in millimeters is confusing me. I would convert all to meters, but I am required to solve using 3sf, so I would lose accuracy on the 2.50mm. Am I correct in thinking the answer is in m/s?
