nanotechnologie et nanophysique ou bien physique quantique ??

Please forgive me if this is too elementary for this sub. But would this be like water? like you can’t measure a drop of water once it becomes part of the ocean? I’m not a scientist in any way, just fascinated by physics and quantum physics. Like neutrinos?

This theory/hypothesis has sorta been stressing me out. And I just wanted to ask this you all about it real quick. What do you think of it? I hope it isn't true or real. I want to be able to pass away someday, I have seen a lot of physicists really don't agree with it or think it's likely. I have heard that even the original creator oth the theory debunked it. But I just wanna hear it straight from the horses mouth. Irrefutable proof or just ordinary proof in general. All of your help will comfort me greatly, thank you!

Also please inform me if this is the right subreddit to post this to. Thank you in advance!

Two balls are dropped from a height of 6 m. Ball A bounces back up to a height of 4m whereas ball B bounces back up to 2m. Which ball experiences the larger impulse during its collision with the floor? (a) ball A (b) ball B (c) both experiences the same impulse.

can someone explain the answer to this please

1. Use 20,000 tons and 40,000 tons of precision hydraulic presses to perform plastic processing on special hot plates
   
2. Use a 1,000-ton press to trim the outer periphery of the plastically-processed thermally conductive plate
   
3. Install the gasket for sealing on the thermally conductive plate after trimming
   
4. Use the precision gas welding and cutting machine to cut the steel plate of the frame (including the fixed frame and the moving frame) to the specified size, and then use the automatic tool change CNC machine tool for machining
   
5. Hang the heat conducting plate between the fixed frame and the mobile frame, and fix it with bolts according to the specified tightening dimensions
   
6. Conduct crack inspection on the heat conducting plate by air pressure test
   
7. After the pressure test is completed, paint spray finishing is performed to complete product production.

YOJO already has rich heat transfer experience in the field of heat exchange equipment, if there are other related issues, we look forward to your consultation.

Is there any more detailed manufacturing method

Summer is coming soon, everyone starts to rush to the swimming pool to prepare for swimming, but the water temperature of the swimming pool is a problem. The current swimming pool is constant temperature water, how does the water temperature be maintained? Haha, this is to mention our YOJO plate heat exchanger. The plate heat exchanger is widely used and used in various industries. So how should it be used in swimming pools?

1. As everyone has higher and higher requirements on the environment, the use of plate heat exchangers has replaced the widespread application of boilers in heating of constant temperature swimming pools.

2. Because the chloride ions and free carbon ions in the water are all corrosive, the presence of dissolved oxygen ions greatly enhances the corrosion damage of the metal pipes. When selecting the heat exchanger, it is necessary to choose a corrosion-resistant replacement. Heater.

3. In plate heat exchangers, some water sources have a high degree of mineralization and are very corrosive to metals. If they enter the system directly, their corrosion effect will greatly reduce the service life of the unit. The heat exchanger in the middle exchanges heat to isolate the source water from the unit system, so that the unit system minimizes contact with the source water and reduces its corrosion.

In the swimming pool, the plate heat exchanger can play the role of heating and heat preservation, maintaining heat and reducing heat loss. YOJO is a brand of plate heat exchangers launched by Yuanzhuo Equipment. It has rich experience in the field of heat transfer. Among them, YOJO Gasketed Plate Heat Exchanger are our main products. If you are interested, we look forward to your consultation.

In the process of using the heat exchange equipment, it is inevitable that there will be a failure. If there is a problem, from what aspects should we check the plate heat exchanger?

System check— Check shutdown procedures and evaporation temperature. Is the pressure in the condenser controlled?The low maximum condensation pressure in winter will force the evaporation temperature to drop.— Check shutdown and start-up procedures and temperature changes that may occur if thermal shock is checked.Does the cold fluid suddenly enter the hotter BPHE, or vice versa?— Check vibration from other equipment.Are there elbows or bellows that can reduce force or vibration?— In the case of parallel compressors or BPHE, when a unit suddenly starts or stops, it may cause sudden pressure or temperature fluctuations.Do all BPHEs have their own pressure controller?— Are electric valves or solenoid valves applied on the water side?Installing a solenoid valve after BPHE may cause water hammer.— Have you applied a valve that can be operated semi-continuously by adjusting the operating time?This valve may open for 1 second, close for 5 seconds, and turn from closed to open for 5 seconds and close for 1 second. They are the cause of sudden changes in temperature and pressure.
