Vessel 1:- I have a cylinder, full of water, with a volume of v. This cylinder has a full sized door at the bottom of it. I understand that if the door is opened the the force of water pushing downwards is the weight of the water in the cylinder.

 

Vessel 2:- It is cylinder with a cone on the bottom of it. Part of the cone has been cut off to create an opening for the water to come out but a door is attached. The volume of this vessel is also v.

 

Question:- If the door of the second vessel is opened does it still have the same force of water pushing downwards?

If I'm not mistaken, the total force the water delivers will be the same, but the concentration or power will vary. Its just like how current acts in electricity. The voltage can remain the same, but the amps can vary.

The tank height is important.

If two tank height is same, we can compare this with the pressure.

At the beginning two tank pressures are same, but as time passes, 1 tank pressure is rapidly drop.

Force is different, 1 vessel force is bigger than 2 vessel at the beginning.

The height may be different, but it still has to have the same volume. So then would there be a difference of force between water coming out of a straw with a height of 3 meters with a volume of v than a cube with a volume of v?

P= lo * g * h

lo; density

g; acceleration of gravity

h; height

Still a bit confused. To clarify the situation. If I used each of the vessels to push down on a spring, would each vessel push the spring down by the same amount?

If there were not gravitational potential field, the water could not flow. There is gravitational potential field. So the water level height does important role on the water flow.
