Ssongoku replied to the thread Correct statement about a reservoir with an outlet pipe.I am not sure what you mean by "each side of the tap" but I will take position 1 to be at the 12 m above the tap and position 2 to be at...

Ssongoku replied to the thread Correct statement about siphon used to empty water tank.In the first link there are several formulas for the pressure but I don't think using any of those formulas can result in P to be zero...

Ssongoku replied to the thread Correct statement about a reservoir with an outlet pipe.I would say it is possible. So if this situation happens, then the water won't flow even though the tap is open? Thanks

Ssongoku replied to the thread Correct statement about siphon used to empty water tank.Approximately correct because the absolute pressure will be zero only at 0 K? Thanks

Ssongoku replied to the thread Correct statement about a reservoir with an outlet pipe.Assuming ideal gas and constant temperature, then as the water level drops, the volume increases so the pressure decreases. Not sure...

Like.
Yes, and the reasoning you give is ok. I would have described it as the flow lines are compressed below so the air pressure is greater... -

See Magnus effect.

I have a feeling I have misled you on statement 1. From experience, there should be downward pressure on the ball. And if the air is...

The arrows on the airflow show the relative motion. If the air is actually still, which way is the ball moving?

Right
