By mini-lecture, experiment, and example
By mini-lecture, experiment, and example problem – you’ll learn how to avoid sucking gasoline to start a siphon, what the max flowrate you can obtain will be, and how tall you’ll need to make it.
Master Fluid Mechanics with my full course playlist: Fluid Mechanics
The continuity equation example problem in this video will show that by varying the length of the siphon, you can control the flowrate. You can find the flowrate of the siphon using the Bernoulli Equation and Continuity Equation. As a Bernoulli equation example problem you’ll be comparing the surface of your tank to the exit of your drain pipe. When the siphon is used to draw water (or in this problem Ethanol), in order to siphon without cavitation occurring, you’ll need to find the saturation pressure of the siphon which will vary depending on the fluid.
Depending on which textbook you are using, Bernoulli Equation and Continuity Equation may be in Fluid Mechanics Chapter 4 or Fluid Mechanics Chapter 5. For this siphon experiment Bernoulli Equation doesn’t fully account for head loss at many points in the system, but is still a good starting point for main concepts. You’ll learn how to account for losses later in the course when studying continuity equation for flow in a conduit, Moody Diagram, Reynold’s Number, Minor Losses, etc.
