If a pipe with flowing water has a cross-sectional area nine times greater at point 2 than at point 1, what would be the relation of flow speed at the two points?
The flow speed at point 1 is nine times that at point 2
The flow speed at point 2 is nine times that at point 1
The flow speed at point 1 is three times that at point 2
The flow speed at point 2 is three times that at point 1
The flow speed relation will depend on the viscosity of the water
