TCNJ Flume (L, H, W): 16 x 2 X 1 feet
The Water Resources Laboratory provides students with
hands-on experience to compliment and strengthen theoretical topics
covered in the Introduction to Fluid Mechanics course. Students
work in teams to collect and analyze data obtained from numerous
pieces of equipment. The lab features a total of nine pieces of
equipment, each of which is designed to enhance a student’s
knowledge of a particular area of hydraulic engineering. The
laboratory equipment with experimental topics are listed below:
-
Flow Measuring Devices
Students use a manometer to measure pressure differences around
both an orifice plate and a venturi meter for the purpose of
ascertaining a relationship between pressure head difference and
flow rate.
-
Pipe Friction Apparatus
Students measure pressure differences at the ends of various
lengths of pipes with different roughnesses and diameters for
the purpose of determining friction factor values.
-
Minor Losses in Pressurized Flow
Students measure energy losses around geometric
changes/obstruction in pipes. This data is used to determine
specific minor loss coefficients around each type of geometric
change/obstruction.
-
Flow Visualization
Students use a Laminar Flow Table to visualize streamlines
around different objects as well various sources and sinks
within the flow field.
-
Series/Parallel Water Pump
Students configure two centrifugal pumps to run individually as
well as in series and parallel. Pump characteristic curves are
developed for each combination and compared to theoretical
expectations.
-
Hydrostatic bench
Students use this apparatus to determine fluid properties as
well as verify theory associated with fluid statics. Fluid
properties determine include: density, specific gravity of
various fluids, and surface tension. Fluid statics concepts
tested include: hydrostatic pressure on submerged surfaces and
buoyancy.
-
Ground Water Table
Ground water flow and direction of movement are determined
through the use of nineteen piezometers.
-
Water Hammer
Students become familiar with the concept of water hammer,
pressure wave oscillations, and the speed of sound in water.
-
Open Channel Flow
Students use a flume to verify a series of topics associated
with open channel flow. Topics covered include: Manning’s “n”
value determination, Specific energy diagrams, Hydraulic jumps,
Flow transitions over hydraulic structures such as V-notch and
broad-crested weirs, Flow transition into hydraulic structures
such as culverts with various types of inlet conditions.
