Fluids Laboratory

Votey 101
1600 Sq ft.
Laboratory Supervisors: Will Louisos and George Pinder

Courses that use the laboratory:

  • CE 162Hydraulics Lab  
  • ME 123Thermo-Fluid Lab
  • CE 265Ground Water Hydrology 

Major Equipment:

  • 6-meter Re-circulating Flume and acrylic weirs (1), Engineering Laboratory Design, Inc. Purpose: The flume is used to create hydraulic jumps, analyze energy losses through the jump, and compare measured and theoretical depths downstream of the jump. Weirs are used in combination with a point gage to measure the pressure head and flow rate under different channel conditions.

  • Hydraulics Benches Armfield F1-10B. Used in conjunction with Venturi meters, sharp edge orifices, centrifugal pumps, and Osbourne-Reynolds demonstrations. The smaller bench format allows students to gain hands-on experience in small groups.

  • Venturi meter, pressure taps and mercury manometers
    Armfield F1-15 – Used to demonstrate Bernoulli’s Theorem. Students used the Venturi meter to determine flow characteristics through a pipeline meter, associated discharge coefficients, and measure the head losses in a pipeline meter.

  • Sharp-Edged Oriface and Free Flow Jet
    Armfield F1-17 – Used to determine the characteristics of flow through a small-edged orifice and to determine the coefficients of contraction, velocity and discharge.

  • Centrifugal pumps
    Armfield F1-27-G – Used to determine the constant speed characteristics of a centrifugal (radial flow) pump. Characteristics include head-discharge, power-discharge, and efficiency-discharge. The motor is instrumented with a Watt meter for power consumption readings. Bourdon-type pressure gages indicate the suction and discharge pressures, and discharge is measure by gravimetric methods.

  • Dead Weight Calibrator
    Armfield F1-11 – Used to calibrate the Bourdon-type pressure gages.

  • Osbourne-Reynolds Apparatus
    Armfield F1-20 – Used to study laminar flow, transitional flow, turbulent flow and associated velocity profiles.  Velocity measurements are used to calculate Reynolds numbers.
  • Hydrometers Custom built – Clear, acrylic, cylindrical tank with seat hole in the bottom and small side drain. Used to study the relationship of hydrostatics as it relates to forces on submersed bodies.
  • Water meter and test stand – Used to study the characteristics of a household water meter and determine its usefulness as a flow measuring device.
  • Flotek 1440 Wind Tunnel Used to study the properties of air flow around various objects including air foils.

  • Tinius Olsen Loading Apparatus – Capacity 60,000 lbs. with screw gear drive and MTS control. The Tinius was a military donation at the time that Votey Hall was constructed in 1964 and has been in use over since. The Tinius is used in the Mechanics of Materials course to test standard specimens of various metals (steel, aluminum, brass, copper, cast iron. etc.) and for testing wood beams, small concrete beams, and student designed balsa wood trusses. It has been used for industrial purposes such initial testing by Burton Snow Boards and numerous other items of interest to local industries.
  • Concrete Compression Testing Machine – Capacity 300,000 lbs. Humbolt HCM-2500. Used to compress student-made concrete cylinders and cylinders collected in the field.
  • Dynamic Analysis Equipment available with accelerometers and impact hammers.Used to test the vibrations of small and large scale models.
  • Surveying equipment  – TopCon laser levels, optical and laser tribrachs, GPS systems, prism poles, level rods and tripods. Used in the CE 010 Geomatics course.
