Wherever you are on a sphere, you are always at the peak of the hump; everything curves 360 degrees around you, however gradually. The hump is commonly portrayed as being in front of the observer, but that can never the case.
Yes, exactly. I thought when you were asking about where the peak of the hump is you meant the peak of the hump relative to the glass container (hence why you said things like "100 feet from the left.") That would depend on the tilt of the container
Seeing that the ground curves in all directions, would we even be able to place this extremely long container on the ground?
Nope! Unless there was a terraformed part of land, I don't think there's anywhere on earth you'd be able to place a container like that flat on the ground
Why would it need to be 1.2 miles deep? at that point, the floor no longer 26 feet below sea level, but 1.2 miles below.
The builders may not account for the curve, but if they are digging relative to sea level., then they never have to. If throughout the whole stretch of the canal the depth is 26 feet, then the base of it actually is curved without them even intending it to be.
.....height....digging depths.....are relative to the centre....so...if I move a few feet....guess what...I am still perpendicular to the surface......lol and that is related to the rotation....relative to a reference point....but....depth....is relative to the centre....not the surface point you start at........so you would curve on every step.....you understand that?
Ie....you don't dig more
.... The ground has sunk with you.....see....you cannot use this argument logically....it's a bad shitty argument.
I am not saying it's a globe...I am saying this argument is stupid and full of holes....big ones....
What you should be doing....is building a ramp that goes up.....8 inches per square mile relative to your starting point....not present point.......and then see if you need to walk up hill hahahaha.
In theory it should be flat if built perfectly (but again ...how do you ensure you have maintained a perfect ramp?) if the world is a globe.
I guess you could cut a straight line which has a known depth and apparently follows the curve....then you calculate the apparent volume and you ramp up half the cut with measured amount of filler which should be based on the so called amount of curvature needed.
Then you have a ramp and a remaining half of the cut is empty space. You should now be able to fill the remaining space with the same amount of volume of water ( assuming non porous surfacing) and then it should perfectly fill the pools space.
If the world is flat then the ramp should not be perfect and then result should be more ddirt than water and it would overflow
water will always act due to the forces of gravity, not necessarily stay "level." It's why when you have instances of zero gravity (such as in the infamous "vomit comet" plane ride used to train astronauts), you'll see water float.
Sea level is relative to the center of the earth though, not the surface of the land. So sea level actually does have a curve
Assuming the container is flat along the top and bottom, the water wouldn't be parallel with the rim of the glass.
As far as the "hump" is concerned, it would be a constant arc. Where the peak of the hump is depends on the position of the glass container.

You would at that scale need to account for the weight of the glass.....and the waters own mass too. Technically.

26 feet is deep enough, so 1.2 miles would be plenty deep for a canal.
Gravity acts on everything, including canals. I'm not sure what your point is...
The whole water "bending" part is a little misleading. Water is a fluid. It's not bending at all. It's filling a container.
You don't.... understand.
