Product Code : SCL-CELE-14021
This apparatus is a compact unit designed to perform the
classic Osborne Reynolds experiment, which visually demonstrates the
transition between laminar flow (smooth, orderly movement) and turbulent
flow (chaotic, mixing movement) by injecting a dye trace into a flowing
water stream.
1. Key Components and Design
The setup is optimized for creating smooth flow and
visualizing the fluid's behavior at different velocities.
- Test
Section (Transparent Pipe): The central part where flow
regimes are observed.
- Material:
Transparent pipe section.
- Inside
Diameter (ID): 10 mm.
- Length: 675
mm.
- Inlet:
Features a flow-optimized inlet to ensure the water enters the pipe
section smoothly and without initial disturbance, which is crucial for
establishing laminar flow.
- Water
Supply:
- Water
Tank Capacity: 200 mL. (This likely represents a
constant head tank capacity used during the experiment, not the entire
sump).
- Dye
Injection System:
- Tank
for Ink (Dye) Capacity: 250 mL approx.
- Function: The
dye is introduced into the center of the flow stream to act as a visual
tracer. The behavior of the dye stream is what determines the flow regime
observed.
2. Purpose and Experiments
The primary goal is the visual verification of flow regimes
and the determination of the critical Reynolds number Recrit.
- Laminar
Flow: At low water velocities, the dye streak remains
straight and distinct, demonstrating laminar flow.
- Transitional
and Turbulent Flow: As the velocity increases (flow rate is
controlled and increased), the dye streak will first become wavy
(transitional flow) and then rapidly disperse and mix with the water
(turbulent flow).
- Reynolds
Number: By accurately measuring the flow rate and calculating
the Reynolds number for the transition points, students verify the
experimental values for the critical Reynolds number.
