2C10.10 - Three Hole Can Experiment - Velocity of Efflux

Code Number:
2C10.10
Demo Title:
Three Hole Can Experiment - Velocity of Efflux
Condition:
Excellent
Principle:
Pressure vs. Water Head Height
Area of Study:
Heat & Fluids

Disclaimer

Equipment:
Plexiglas Column with Holes, Catch Basin, Mounting Platform and Ring, and Large Beakers with Water.
Procedure:

Video Credit: Jonathan M. Sullivan-Wood.

Mount the Plexiglas column on the platform at a height so that the water will shoot into the catch basin.  Fill the column with water and observe the Pressure vs. Water Head Height relationships as demonstrated by the water streams.
