And if you have to choose between the two?

I'm talking about the total energy consumption. Let’s say you have a glass with 50cc of water at room temperature and you need to evaporate it completely and return it empty, while using as little energy as possible, and let’s also assume that the duration is not important here. You have to...

Ok thanks- so why does moving the state closer to the dividing line between phases makes the total energy consumption lower?. scientific words are ok, as well as intuitive explanation.

Yes, perhaps the right question is: In which evaporation process is the total energy consumption lower and why — heating water to 60°C or placing it in a vacuum chamber? (at both starting temperature is 25C) From a physical process perspective, why does it take less energy to evaporate water...

Thanks all, so the net energy required is the same also for the following evaporation scenarios? Glass filled with 50cc of water at 25C; the water is heated to 60C Glass is filled with 50cc of water at 25C; the glass is placed inside a vacuum chamber. Does the net energy required to...

The latent heat depends on the temperature, but are right- this might be the reason.

If you put a glass of water inside a oven at 60C, the water will evaporate. Correct?

Energy required to evaporate water. Given 3 evaporating scenarios: 1. Glass filled with 50cc of water at 20C; the water is heated to 60C 2. Glass filled with 50cc of water at 20C; the water is heated to 100C 3. 50cc of water at 20C wiped over a large plate to create 50micron thickness layer...

Roundness is 50micron. If the parts are assembled with no force required, and have similar thermal expansion coefficient, then the question, I think, what is the effect of adding glue between them, with high thermal expansion coefficient. The parts are rigid, and the glue is polymer. Can it...

No axial constraints. OD 130mm (unstressed diameter) ID 100mm

Yes, you can merge them.

Yes, it meant to bond them. Since the ceramic and steel have a similar thermal expansion coefficient the gap between them is never closing (at steady state). but the gap is filled with this glue, which expands. A 100 micron thin flat layer of glue barley expands in absolute values. But in my...

I’m trying to understand if in principle a very thin layer, with high thermal expansion coefficient, but low modulus is placed between rigid cylinders - can it extract significant forces? I imagine it more as a soft spring.

[Mentor Note -- Two threads on the same question have been merged.] I have two concentric cylinders, the inner cylinder is made from stainless steel on the outer cylinder is made from ceramic. The inner cylinder is heated. The cylinders are glued using epoxy glue. The gap between the cylinders...

I have two concentric thick cylinders in close tolerance (currently 50 micron gap), with a thin layer of glue between them. Internal cylinder is made from steel and external cylinder is made from ceramic (so the thermal expansion coefficient is not the same) The assembly is headed form inside...
