Equipment Safety Notes
1. -Do not run the pump with the flow and the bypass valves closed. A completely
closed discharge side (dead-headed pump) will increase the temperature of the
water inside the pump, which could lead to seal and/or pump damage.
2. -Do not allow the pump to run dry (no water) as this will result in failure of the
shaft seal.
3. -Always look for leaks. Immediately report any leaks to the lab supervisor. The
main flow valve and bypass valve may drip during use. These are the ONLY “OK”
leak locations.
4. -For loop “B”, do not fully close the globe valve. The maximum differential
pressure reading must not be greater than 30 – 34 psi.
a. -Equipment terms are shown in the figures at the end of this section
b. -All valves open with a counter-clock-wise turning action
Initial Start-up
1. Energize the electronic meters
2. Open all four loop selector valves
3. Open fully the globe valve on loop “B” (Turn counter-clockwise all the way)
4. Open fully the main flow valve (Turn counter-clockwise all the way)
5. Open fully the pump bypass valve (Turn counter-clockwise all the way)
6. Check the digital (red) flow rate meter. It should read 0.000 US GPM
7. Check to make sure that there is water in the tank
8. Energize the pump
9. Wait 10-15 seconds for air to be expelled out of the system
10. Check the calibration of the digital (red) flow indicator by using a stopwatch and
the analog volume meter. You may slowly close the bypass valve to increase the
water flow through the experiment. Any gallons per unit time measurement
should work to check to make sure the digital (red) indicator is calibrated.
11. Check to make sure that the loop differential pressure between the pressure taps,
indicated by the differential digital (green) indicator, is working. Note that the
upper and lower manifold pressure gauges are NOT in operation.
– Check the plastic differential lines for water. The presence of air in the lines
will change our “true” readings.

Open one of the four loop selector valves, make sure the other three are closed
If loop “B” is to be used, fully open the globe valve
Open fully the main flow valve
Open fully the pump bypass valve
Start the pump
Wait 10-15 seconds for air to be expelled out of the system
It is usually easier to start with a low flow rate and work your way up to a high one.
Repeat steps for other loops.
a. For loop “B”, do not fully close the globe valve. The maximum differential
pressure reading must not be greater than 30 – 34 psi.

Fluid Flow Experiment
The performance and evaluation of general piping systems are strongly dependent upon
flow measurement devices and energy losses in the fluid through viscous dissipation. An
engineer dealing with internal flow systems must have a solid understanding of the flow
physics in the system, including the parameters and associated sensitivities that affect
system performance.
Objectives
The objectives of this experiment are to measure the friction and loss coefficients associated
with fluid flow, and to compare these results with expected results based on the literature.
The following should be determined over the range of fluid flow that is available:
A. The friction factor – Reynolds number relationship for water flowing in a
straight copper pipe.
B. The estimated equivalent lengths of two types of elbows (45-degree and
90-degree) and one open globe valve.
