Welcome to Fawick 011, the Hydraulics lab. The lab contains the equipment to demonstrate fluid dynamic principles in pressurized-pipe and free-surface flow conditions.
Lab procedures allow students to evaluate real-world design concepts in hydraulic engineering by applying the fundamental equations of energy, momentum, and continuity. In each lab, students participate in hands-on physical experimentation using a different apparatus. The students document, graph, and analyze the experimental data, and interpret the results in an engineering lab report.
The central piece of equipment for each experiment is the hydraulic bench. There are two of these benches in the lab. Each bench contains a manometer, an internal reservoir of water, and a submersible centrifugal pump. The benches can produce flows up to a rate of approximately 1.5 liters/per second. Students measure volumetric flow rates using the manometer and stopwatches.
In each lab, a different apparatus is attached to a hydraulic bench to analyze specific hydraulic principles. These attachments include:
A Bernoulli apparatus, which demonstrates the inverse relationship between pressure and velocity pressurized pipe steady flow conditions.
A pipe network, which demonstrates losses in pressurized pipes in series and in parallel. It also demonstrates the impact of pipe diameters on energy loss.
A bend loss device, which demonstrates minor losses around bends, as well as losses through expansion and contractions.
A much larger pipe network, which demonstrates losses around bends, losses based on pipe diameters, losses based on the pipe material, and losses through valves, Venturi tubes, losses through an orifice, and losses through expansions and contractions.
An external centrifugal pump, which demonstrates the pump performance characteristics. This external pump, when used in combination with a pump inside a hydraulic bench, demonstrates pump hydraulics when operating in parallel and in series.
A cavitation device that demonstrates the vaporization of water due to high velocities and low-pressure conditions.
A Pelton turbine demonstrates the conversion of linear momentum into angular momentum and a linear momentum apparatus that demonstrates the impact of a jet of water a flat and a curved plate.
A 6-foot tilting flume demonstrates the effect of slope on open channel flow, allowing students to observe supercritical and subcritical flow conditions, and observe gradually varied flow profiles in steep-sloped and mild-slope conditions.
A horizontal flume is used to demonstrate several important open channel hydraulic principles, including specific energy, critical flow conditions, hydraulic choke points, and conservation of momentum through a hydraulic jump. This flume is also used for the student-developed lab to evaluate flow over sharp-crested and broad-crested weirs.
A velocity meter that can be used to measure velocities in streams.
The hydraulics lab is also home to the surveying equipment used in CEE 2001. The main equipment utilized by the students include: Topcon AT-G2 Auto Levels, Topcon ES-105 Total Stations, Topcon Hiper SR GNSS rovers, and Topcon Tesla data collectors loaded with Topcon Magnet Field software. Additional surveying equipment and supplies including rods, prisms, tripods, fiberglass tapes, folding rules, flagging, hubs, lath, etc. are available for student use.
We hope to see you on campus soon to tour our Hydraulics Lab in person!
