In this comprehensive tutorial, we look into the H215 Osborne Reynolds Apparatus, a powerful educational tool that allows students to observe and measure laminar, transitional, and turbulent flow in a fluid. Through hands-on experiments, students can calculate the Reynolds number and understand its significance in fluid dynamics.
Key Features and Components:
- Reservoir System: Learn how the constant head of water is maintained via an overflow system to ensure accurate and consistent flow measurements.
- Glass Tube Flow Path: Follow the path of water from the reservoir, through a glass tube, and finally into a drain or collection vessel for flow rate measurements.
- Ink Injection Method: Discover how a fine needle injects ink into the water stream to visually demonstrate different flow regimes—laminar, transitional, and turbulent.
- Temperature Control (H215a): Explore the optional H215a module that allows for temperature adjustments, enabling students to observe how temperature affects the Reynolds number.
00:00 Exploring the Osborne Reynolds Apparatus
02:18 Setting Up the Apparatus: Watch how to connect the water supply, ensure a clean and consistent flow, and prepare the system for experiments.
03:20 Creating Laminar Flow: Learn how to adjust the valve to create a smooth, steady flow of ink in the glass tube, representing laminar flow.
05:55 Observing Transitional Flow: See how slight adjustments to the valve create a mixed flow regime, where the ink starts to show signs of agitation.
06:45 Achieving Turbulent Flow: Fully open the valve to observe chaotic, turbulent flow and understand the conditions under which it occurs.
07:15 Measuring Flow Rate and Temperature: Get tips on how to accurately measure flow rates using a jug and stopwatch, and how to record water temperature for further calculations.
07:35 Calculating Reynolds Number: After gathering data, students can calculate flow velocity, viscosity, and ultimately, the Reynolds number to differentiate between flow regimes at various temperatures.
