Njoro New Member Njoroge Join Date: Aug 2019 Posts: 1 Rep Power: 0	Esteemed members, Can someone help me on how to work out the actual velocity from a published result? I have tried a few tricks that I know but it doesn't work. Say for example, having u/U=10.(I assume u to be instantaneous velocity at a point while U is the mean inlet velocity). so I get my u=U*10. The problem with this is that it is physically not correct. Am working on a sudden contraction/expansion channel. Can someone help?
