ya sorry ..I phrased it poorly.
I This question is part A. I can calculate a velocity 10.2 m/s which does appear on the list yes.
However when I move to part B it wans to know what the velocity V3 of the lower section is.
I use conservation of mass to determine this and i get an answer of...
attached is the problem. I use bernoulli's equation along a "streamline" from the inlet at point 1 to outlet at point 2. I do this to obtain the velocity V2. After working through it (simple algebra) I end up with 10.20 m/s ...seems right to me... however upon doing a conservation of mass...
