Problem Set
6



Problems from Munson, 6
th
edition:


Conservation of energy

5.90


5.92, 5.94

Hold off on problem
s

5.95
and 5.97
for now. We may add
them

later

5.96


One assumption this problem makes that may initially be surprising is t
hat
V
1

= V
2
. Think about why that is.

5.99



T
o solve

this problem assume steady, inviscid, incompressible flow along a
streamline

(use Bernoulli)

5.101

5.104

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

5.108

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.

5.109


5.11
1
For
5.
111 it will be helpful to know that 1 ft
3

= 7.48 ga
llons

5.112



A
s in problem 5.96, assume V
1

= V
2

(why?)

5.113

5.116

5.118

119

5.121

Combining conservation of energy with linear momentum

5.124

5.125
T
his problem has a non
-
uniform velocity profile. You will need to make
use of the information in section 5.3.4 (or class note
s on this topic)



5.126


5.130


5
.131
As in problem 5.25,
t
his problem has a non
-
uniform velocity profile.


Probl
ems that are fun to think about. Look over the solutions,
but you don't
actually need to do them

5.98,
5.105, 5.117
, 5.132, 5.133
