HYDRAULICS LABORATORY
The Hydraulics Laboratory is
located at the basement of the Engineering Building. It provides approximately
150 m2 of working area. With the arrival of new equipment, the
laboratory has become operational in 1997 and has being used mainly for
undergraduate courses since then.
In Spring 2001, the laboratory
has undergone a major renovation. With the financial support of Garanti Bank,
new floors, power, water supply and air ventilation systems have been
installed. The existing concrete channel has been removed to double the
effective area of the laboratory. With this addition, the hydraulics laboratory
is now capable to accommodate experiments for graduate courses and research
projects.
Probable causes of hazards in the
laboratory and safety precautions are explained in the laboratory handouts
given to the students at the beginning of the semester and discussed by the
instructors. The assistants are made aware of safety precautions and are
responsible for checking of the equipment and warning the instructors if
maintenance or repairs are required. Fire fighting equipment is available in
the hallway leading to the laboratory.

Centre
of Pressure Apparatus
H11 Mk II by TecQuipment
This apparatus permits the moment due to the total fluid
thrust on a wholly or partially submerged plane surface to be measured
directly and compared with theoretical analysis. Provision is made for
varying the inclination of the plane surface subjected to the fluid pressure
so that the general case may be studied
.

Advanced Hydrogen Bubble Flow Visualization System
F14
by Armfield
This
bench-mounted equipment has been developed to meet the need for direct
visualization of fluid mechanics phenomena. The very small
size of the hydrogen bubbles generated by the fine platinum wire ensures a
faithful visualization of an undistorted flow situation.

Sediment
Transport Channel
S8
by Armfield
This
apparatus is designed to demonstrate two principle methods of sediment transport
in water: Bed load and suspended sediment transport. In addition, experiments
have been suggested that will demonstrate local scour at channel obstructions
such as bridge piers, and the secondary flow in channel beds

Reynolds
Number and Transitional Flow Demonstration Apparatus
H215
by TecQuipment
This
apparatus demonstrates the dependence of flow on Reynolds Number using a
filament of dye injected into the fluid. The flow rate can be varied and the
transition between laminar and turbulent flow can be clearly demonstrated.
The effect of viscosity on the behavior can be shown by varying the
temperature control module, or by using different fluids.

Losses in Pipe Fittings
H34
by TecQuipment
This
experiment illustrates losses in typical pipeline fittings
such as bends, changes in diameter, junctions and valves. The constrictions,
and changes in direction of flow, through such fittings cause losses, which
are additional to those due to friction at the pipe wall.

Hydrology
Apparatus
H313
by TecQuipment
This
apparatus enables the various factors related to the rainfall-runoff process
to be investigated. The overhead sprinklers supply the rainfall to the
catchment, which may be varied in slope and the permeability of which will
depend on the media chosen. A special feature is the ability to supply rain
to either the upper half only or all of the catchment and to simulate storm
movement by switching from one to the other.

5
Metres Inclinable Flow Channel
H12
Mk II by TecQuipment
This
is a hydraulic flow channel designed for demonstration of the general
features of open channel flows. The channel operates in a closed water
circuit. Water from the supply tank is pumped to the channel inlet through a
precision control valve. A particularly useful feature is that the valve may
be adjusted by a control rod from any location along the length of the
channel. From the outlet the water drops into a gravimetric measuring tank
and then returns to the supply tank.

Wave
Probe Monitors
CLE3
C30 by H R Wallingford
The
wave probe monitor is a simple, reliable device for the measurement of water
levels. It operates on the principle of measuring the current flowing in an
immersed probe, which consists of a pair of parallel stainless steel wires.
The current flowing between the probe wires is proportional to the depth of
immersion and this current is converted into an output voltage proportional
to the instantaneous depth of immersion. The output circuitry is suitable for
driving both a chart and a data logger.
