What you describe would be true, only if the increase in pressure(kinetic energy) would come ONLY from water in the tube dropping(permanently), hence potential energy from the water in the tube. IF however, the water in the tube does not drop by that amount, then the kinetic energy to pressurize the water in the container would also come from atmospheric energy(sun, air heating up the tube). Therefore, water molecules in the tubes passing kinetic energy to the container molecules just to be heated up again by the sun/air. Which would also mean that the water in the tube would cool. | |

Judging from your new explanation the paddle wheel does nothing to get at what you want to determine and you really want to measure the temperature change of the water do to the pressure change. Again, give it a try and see what happens. | |

IF after opening the red valve or shutter the water in the tube would drop exactly by the amount required to pressurize the container water. Hence, transforming potential energy of the water in the tube into kinetic energy of the water in the container. If it does not drop by exactly that amount, then the energy has to come from other than sources as well, other than just potential energy. | |

The question is if this process can continue indefinitely, getting energy out of the system which is NOT just potential energy from the water dropping down. Hence, if there is also energy involved drawn from the atmosphere as the water heats up again through the air/sun. What i got from the answers so far is that i have to refine the experiment to make it more clear. | |
