Here’s a simple experiment to demonstrate connector drainage, which illustrates how fluid flows through connected vessels or tubes due to gravity and pressure differences. This concept is often applied in plumbing, medical devices, and engineering systems.
Connector Drainage Small Experiment
Objective: Observe how liquid drains from one container to another through a connecting tube due to gravity and air pressure.
Materials Needed:
Two clear containers (e.g., plastic bottles or cups)
A small tube or flexible straw (connector)
Water (colored with food dye for better visibility)
Tape or a stopper (to secure the tube)
A tray or basin (to catch spills)
Steps:
Set Up the Containers:
Fill Container A with colored water.
Leave Container B empty and place it lower than Container A.
Connect the Containers:
Insert one end of the tube into Container A (submerged in water).
Insert the other end into Container B.
Ensure the tube is filled with water (no air bubbles) for smooth drainage.
Observe Drainage:
Once the tube is filled, water will flow from Container A (higher) to Container B (lower) due to gravity.
The flow continues until the water levels in both containers equalize or Container A is empty.
Key Observations:
The liquid moves due to gravity and pressure difference (hydrostatic pressure).
If the tube has air bubbles, drainage may be slower or stop (similar to a siphon breaking).
The flow rate depends on the tube diameter and height difference.
Scientific Principle:
This demonstrates Pascal’s principle and communicating vessels—liquid in connected containers seeks the same level due to equalized pressure.
Applications:
Siphons in aquariums
IV fluid transfer in medicine
