    Springs: Can they be used to conserve energy?

    I will post a sketch and explain the relationships of various components, just not at this moment. I have to tend to some tasks at this time that will eat up most of the afternoon but should be able to post this evening

    Springs: Can they be used to conserve energy?

    Through mechanics, potential energy is released by the controlled falling of a suspended mass. At an idling condition, a one tonne mass is allowed to slowly fall. The pushing force of that mass is used to maintain a set rpm of a flywheel. The flywheel shaft drives an electric generator. At a...

    The effects of absolute zero temperature

    Unfortunately physics is not a strong suit of mine. Things in the world of quantum are not second nature to me and explanations and theories sometimes appear open-ended to me. I still have to consider that math is an exact science. When it comes to a point where 1+1=3, I will try to gracefully...

    Fluid dynamics problem: Equalize the volume of water in tanks at differing heights

    erobz. I appreciate the suggestions and interest generated on this question.I have gone ahead with the process of lowering the static start pressure in the upper tank by 3 psi. Fill rate seemed acceptable for both tanks. When initially seeing this system, the lower tank appeared 100% full and...

    Fluid dynamics problem: Equalize the volume of water in tanks at differing heights

    This was also my perspective on the situation. When I came upon this project, the bottom tank was at least 90% full and the top tank virtually empty. Due to slow leak? Maybe. Due to what you describe above? Maybe. IDK. Experimentation is possible but quite problematic since it is desired to not...

    Kill-a-watt meter -- What does it measure?

    You are correct on those issues. I responded to this thread because Kill-a-Watt meter is the brand name ,of the meter I use to track my power usage. I rarely use any other functions other than kWh and clock. I did scroll thru its other functions just now. It does display current watts, VA, and...

    The effects of absolute zero temperature

    Yes, I agree that reference to an electron "orbit" is an oversimplification of an atom's structure. It does seem to be a decent representation for no more involvement than I have with the subject. My acquaintance with atomic structure pretty much ends with electrical conductors are made up of...

    Fluid dynamics problem: Equalize the volume of water in tanks at differing heights

    The reason the tanks are pressurized is to maintain water flow to the water outlet, of course, rather than rely on "gravity flow." For example purposes let's say both tanks are above the water outlet. The initial state of the tanks is that one tank is five feet higher than the other tank. Both...

    Fluid dynamics problem: Equalize the volume of water in tanks at differing heights

    I am working on a reverse osmosis water system. There are 2 bladder type pressure tanks for storage. One tank is at floor level, the other tank is supported directly above the lower tank 5 feet above the floor. It would be advantageous if these tanks would fill at an equal rate, or approximately...

    The effects of absolute zero temperature

    Is the velocity of an orbiting electron constant?

    The effects of absolute zero temperature

    I can visualize gas molecules, contained in a vessel, randomly bouncing into each other. As temperature increases, the collisions occur more rapidly. I suppose this also applies to liquids. I'll guess that a liquid's boiling point is where the molecular collisions become so violent that...

    Kill-a-watt meter -- What does it measure?

    I have been using a brand name "Kill-a-Watt" meter for several years. Quite happy with its performance. My guess as to its accuracy would be 95%. I base that guess upon a device's printed power rating and the meter's readout. A killawatt meter measures and records a device's power consumption...
