Brine at 160°F (SG=1.04, m=10^-3 Pa*s) is drawn at a minimum rate of 250 gal/min from a tank
into the 4-in suction line of the pump. The suction line has a total length of 10 ft.
The 3-in discharge line elevates the water 15 ft to the level of a large heat exchanger. The
discharge line has a total length of 40 ft.
The flow splits into two branches with the primary 3-in line feeding a large heat exchanger that
has a K-factor of 12 based on the velocity head in the pipe. These branches were examined in
Part 1 of the project.
Determine the system resistance operating curve for the system.
All pipes are Schedule 40 steel.
For this system, operating at the desired operating conditions, determine the following:

a. The pressure at the pump inlet
b. The NPSH available at the pump inlet
c. The pressure at point A before the branches
d. The volume flow rate through the heat exchanger line
e. The volume flow rate through the bypass line
f. The total head on the pump
g. The power delivered to the water by the pump. Then specify a suitable pump for this system
that will deliver at least the desired 250 gal/min of flow.
h. For the selected pump, determine the following:

The actual expected flow rate produced by the pump at the operating point
The power input to the pump
The NPSH required
The efficiency at the operating point.
Present your design and rational in a properly written technical paper.
This doesn’t have to be super fancy. Just make sure you’ve got your introduction, results, discussion, and conclusions (and any other sections you feel are appropriate).
