Question

Consider water fl owing by gravity through a short pipe

connecting two reservoirs whose surface levels differ by an

amount D z . Why does the incompressible frictionless Bernoulli

equation lead to an absurdity when the fl ow rate

through the pipe is computed? Does the paradox have

something to do with the length of the short pipe? Does the

paradox disappear if we round the entrance and exit edges

of the pipe?
