1. ### Can I pass liquid through fiber optic strands?

...us narrow the search? Depending on the flow rate you need, viscosity of your liquid, and distance the pressure required can get quite high. John

2. ### Is this a propper analogy to understanding how current, voltage, and resistance work?

...= N*m/C = J/C = Volts. In the water pipe analogy: Pressure Gradient (∇P) is in units of Newtons/meters^3; it is analogous to E-field...

3. ### Is this a propper analogy to understanding how current, voltage, and resistance work?

...he apparently wasn't using the analogy incorrectly. You can have pressure in a pipe without water flow, just as you can have voltage in a...

4. ### Is this a propper analogy to understanding how current, voltage, and resistance work?

...too long since he was learning from the start. Voltage is the pressure push or pulling on the electrons. Resistance is the opposition to the...

### Measuring pressure, force or tension

I'm working on a little project to measure the power put out by a cyclist while riding. The usual way of doing this is with strain gauges, my...

6. ### Looking for a low-frequency amp circuit (2 hz to 20 hz)

the rotary vane is a good idea, but I cant find a supplier for such a compressor meeting all these requirements

9. ### Is this a propper analogy to understanding how current, voltage, and resistance work?

...If you need an analogy, consider that voltage is a sort of pressure, and current is a sort of flow. And resistance is a bit like a restriction...

10. ### Looking for a low-frequency amp circuit (2 hz to 20 hz)

and when I say the compression is from 1 atm to 1.5 atm , I mean absolute pressure, not relative.

11. ### Is this a propper analogy to understanding how current, voltage, and resistance work?

...with the water analogy I get confused because if you have alot of pressure, but a small opening water can end up cutting metal. Can the same be...

14. ### Looking for a low-frequency amp circuit (2 hz to 20 hz)

If you are careful you could probably make a diaphragm pump that runs off of mains voltage.
