The discussion revolves around calculating the glass thickness required for a bottomless aquarium, specifically considering the effects of air pressure holding water up. Participants explore the implications of pressure at various heights and the conditions under which a vacuum may form in the aquarium.
Participants do not reach a consensus on the best approach to calculating the glass thickness or the nature of the problem itself. Multiple competing views and uncertainties remain regarding the physics involved.
Some assumptions about pressure dynamics and the structural integrity of the aquarium glass are not fully explored, and there are unresolved questions about the specific calculations needed.
What do you expect the pressure to be at the same level as the surface of the pond?Jerry Jewell said:How do I calculate glass thickness on a bottomless aquarium where air pressure is holding the water up. Example: 18"x18" by 36"' high closed top. 6" of the aquarium is submerged in a pond.
Thanks.
And if you answer those questions I asked you'll understand the physics involved well enough to do the calculation for yourself.Jerry Jewell said:Hi
Thanks.
I need to know how to determine the pressure at the highest pressure point in order to calculate the thickness of the glass needed for various sizes of bottomless aquariums.
We've been waiting for you to post your answers to the two questions posed in post #2 of this thread. If you aren't sure, go with your best efforts.Jerry Jewell said:If it's so simple why hasn't anyone done it ?
Use the search function, we had this already. The key is: A normal aquarium frame is designed to hold the glass against the force from the inside, not from the outside.Jerry Jewell said:How do I calculate glass thickness on a bottomless aquarium where air pressure is holding the water up.
