5.95
and 5.97
for now. We may add
them
later

One assumption this problem makes that may initially be surprising is t
hat
V

= V
2
. Think about why that is.

this problem assume steady, inviscid, incompressible flow along a
streamline
(use Bernoulli)

Assume the elbow is in the horizontal plane before trying to solve this
problem

Assu
me there is a free jet at the exit. The dimension provided for the jet
at the exit (1 meter) is the diameter of the jet.

ems that are fun to think about. Look over the solutions,
but you don't
