Reynolds Apparatus

The unit consists of a Acrylic tube connected to a tank. At entrance of tube a bell mouth section is provided and at the other end a valve is provide to control the rate of flow. A capillary tube is introduced centrally to the bell mouth to inject die. By varying the rate of flow the Reynolds number changes. This also changes type of flow. Visual observation of die (thread) will indicate the type of flow which can be confirmed from the REYNOLDS number computed.

FEATURES

• Steady flow arrangement
• Very clear flow visualization
• Fine control of die thread.
• Accurate flow measurement & control.

SPECIFICATIONS

• Acrylic tube (transparent) 25 mm OD / 20 mm ID of 1 meter length.
• Main Tank - 400X400X700 mm
• Constant Supply tank of 200x200x 200
• Flow control valve.
• Dye tank and syringe
• Measuring Flask & stop watch for flow measurement.

RANGE OF EXPERIMENT

• To determine the Reynolds number & hence the type of flow either laminar or turbulent.
• To determine upper & lower Reynolds number & velocities.
