Question:

Hydraulics question, with a tapered pipe. If I put the wide end into a river and have the narrow end raised

above the level of the water, will the river force some water to flow uphill, out the open end, especially since the pipe is narrower at the upper end? Since water is incompressible, would this be a physically feasible way of raising water a small distance to fill a small pond or large basin? I realize I'll have to put a filter to remove algae, etc. I don't have the resources to build a mill pond like for an overshot wheel. (This is for a remote site where no electricity or gasoline for a pump is available, but the river current and the pipe are already there.) I only want to lift the water about fifteen feet max and I don't need a very large rate of flow, maybe three or four gallons per minute. The pipe is about 40 feet long and has a uniform conical taper from 8 inches to 31/2 inches. Is there an equation I can use to calculate this? If this isn't clear, please let me know and I'll add more details. Thanks to everybody who answers!3 MAY 08, 1748 hrs, GMT

Answer:

If i were you I would go to court, and fight it if you feel it is unjust. A valid arguement however, is that if you knew the weather or road conditions were not very good, why did you gain enough speed or not slow down enough beforehand for the stop sign. The officer probably followed you both to run your vehicle through the computer, and to observe an other violations
no. he thought you were going too fast.
If I could get someone to do the painting then yes that might be a possibility.
You can fight a ham sandwich, but honestly, this is irrelevant. You have a responsibility to stop at the stop sign . . . if you didn't have studded tires and/or chains, and/or your speed was too fast to allow you to stop on the snow packed and icy road and you had gotten into a collision you would have been ticketed for speed too fast for conditions along with running the stop sign. I'm sorry, but you don't get a pass for icy roads and it's not his responsibility to write down the reason you claim you ran the stop sign. You have the right to request a court hearing. And it's possible you will find a sympathetic judge . . . but I wouldn't count on it. Public policy is that drivers need to be much more careful in poor road conditions.
