Is head loss due to flow expansion/contraction a function of velocity or velocity^2 under laminar conditions?
i.e., in the Bernoulli's eqn, should one write Kv^2/2g or Kv/2g? I know that the K for a long pipe is proportional to 1/Re leading to a dependence only on v. But I'm not sure about minor losses. |
