1) The radial velocity "must" be bigger at the outlet you say, but can water stretch? 2) We multiply Vw2 by U2 but why multiply??? Of course, you must be right but its hard to see. 3) "Weight" of water. We have cubic metres. The weight is 1000 kg wt, which is 1000g N, so does your g get cancelled? Thank you kindly in advance
May you please start teaching again your way to teaching is really good
At 12:36 if Beta is acute angle then sign should be positive?
