oh no no Jim...I didn't feel you get curt on grumpy at all ! I thought you were really patient and helpful bud.
I was just an average student...and probably average intelligence. I don't think i would have made it past engineering school. But now that I am approaching 50, I am fascinated...
Thank you so much for your help Jim...really appreciate your time and expert input. I was suspecting that because it was sealed that there was something not correct. You explained my suspicion about the vacuum in the sealed cylinder. I understand now why you say the large piston will go higher...
The pressure i assume is higher on the side of the large piston because the sealed cylinder level is now higher. Remember that this sealed piston top was at same water level before as that on small diameter piston. If the small diameter water level can push down and raise the large piston...
ok sorry Jim, my last post I meant to say the column on the right on top of the large piston. If that one is sealed, then how can the small diameter piston move down? Wouldn't that move the column on the large piston up and then the hydrostatic pressure on the right side be much higher?
Jim, you say that the large piston would rise now and the water level in the left (open piston) goes down now. But I am assuming there is no way the water column on the left (which is closed), could fall and create a vacuum, and also then, if the large piston rises, the water level in the...
@Jim - thank you. I was more curious about # 3 because I was thinking that both columns were adding a hydrostatic pressure upward on the bottom of the large piston. I was then thinking that it wouldn't be just some small incremental force, but some magnitude large enough to first overcome the...
I have some questions in regards to a diagram that has a twist to the regular set up that is usually used with demonstrating Pascal's law and pistons.
In the diagram I have attached, if you added a column of water on top of the large piston which is sealed at the top from the atmosphere, there...
Can someone tell me what is the best way to attach a picture or diagram on my posts? Something that shows on my post without the reader having to open an attachment??
I know my questions are strange. To be honest Russ, i have a patent that I am trying to market which has relevance for my strange questions. And no, it's not some kind of perpetual motion wheel in the water...most people think that right away.
I appreciate your help as always Russ.
eah, i know river don't flow that fast. I was just using examples for calculations. Was just thinking about the Verdant power company putting in all those small turbines in the Hudson River to catch tidal flow. Curious about their economics cause i heard it was so tough to put in the turbines at...
So 50,000,000 Joules give or take. That seems more right than 50.
So if it was a really long river, it would be viable to put as many of these in as possible? I guess the last one may theoretically receive less because the water may be slowed down by the previous ones? I wonder why they...
