A water main.

Water is cruising through it in a real big hurry.

Is that not creating a vacuum / 'negative pressure' that pulls the inside of the pipe toward the water that is rushing over its surface ?

Potentially odd but related thought:

If such a pipe were 'rifled' would the fluid build and maintain angular momentum ?

If so, would that not be a centrifugal force pushing against the inner walls of the pipe ?

Often I have seen utility companies prefer this construction: they bundle the three phases close together using plastic star looking separating insulators. Why do some power comapanies prefer this? Does the advantages outwiegh the cost?

In the news on Sept 20 it says the State of Californiasued GM, Chrysler, Ford, Toyota, Honda, and Nissan because they did not use technology to limit the emissions of carbon dioxide. Do they know of some present technology or are they trying to force the auto makers to develop something new? Or do they really want more increases in gas mileage so a car burns less gas?

I'm sure the exact answer is variable but is the response time in milliseconds and is it dependable under stable conditions? If I put 2 PIR's on my front fence and measured the time between responses as a car went past, will the system respond quickly enough for me to calculate the speed of the car?

I was told that you could be paid by the power companies to generate power, connect it to their grid, and they just send you a check at the end of each month. So long as you can keep the wind or water turbines turning and don't use more power than they produce you get paid that is. If you were very motivated you could even connect a bike to a belt system and do it that way. The companies were supposed to have a program setup for this and I'd like to be able to get in on it if anyone has heard of, or uses this system and thinks it is also a good idea.

how do you find thevenin equivalent circuit using SPICE??
here is a diagram of the circuit.
http://img.photobucket.com/albums/v233/jster28/1-1.jpg

I need to generate an input file or netlist to show the thevenin equivalent from the terminals x and x'. Would i add a voltage source in circuit with 0V to create a short but, i have no idea where to put it. Can anyone generate the input for simulation for me. Thanks
