A correspondent from St. Pauls, Minnesota, which place is situated on the east bank of the Mississippi about 100 feet above the river, states that the current is very strong there,and he wishes to know what is the best way to obtain a large supply of water by raising it from the river. He enquires if it can be raised by the force of the river operating a spiral current wheel, which might work a pump, or by a hydraulic ram. He tells us that this subject is full ot interest to a great many cities and villages situated on river localities. If the velocity of the current was known, and the nature of the banks of the river above the city for a mile or more known, a i better judgement could be formed of what machine was best adapted to supply the place with water. A hydraulic ram, perhaps, would answer very well; a steam engine we know, would positively answer, but it may be too expensive.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
