Heat Transfer Through Layered Wall

D definitely corresponds to the profile with a turned-off heater, and the lowest conductivity layer is layer 3,Since the heater is a heat source, the temperature profile within the heater layer is going to be parabolic. You can show this by solving the steady state heat conduction equation for the case of a heat source within the material. So, on this basis, profiles A and B are possible. However, in profile A, heat is flowing into the interface between layers 1 and 2 from both sides. This is impossible for steady state operation. So profile B is the profile for the turned-on heater, and profile A is impossible.Profile C is also impossible since heat is flowing out of the interface between layers 1 and 2 on both sides, which is inconsistent with steady state operation.So profiles A and C are both impossible

1. Reliable Source of Heat for Underwater Society? [duplicate]

What you need is a source of heat that could survive underwater. A few ideas come to mind.Plasma. Plasma would not need to consume oxygen to heat things up. A device that could heat up fuel to plasma state is not too far from reality. In fact, we've been using such things in metal machining. Though it might burn too hot.Lasers. Lasers, if powerful enough and concentrated, can burn through metals. This one has an advantage of being more controllable. as you can choose how much power you are putting into the laser

2. Drawing Heat?

When they called Stephanie McMahon something and then Triple H goes "SHUT YOUR HOLES, I'M NOT IN THE MOOD!" that was awsome!!!

3. Is there any chance to increase temperature without supplying heat?

Friction is other way to increase the the temperature of substance .Friction increase the temperature due to transfer of energy into heat. Friction directly proportional to heat generated

4. Replacing your heat sinks with thermal paste

The original Obelisk heat sinks used small clips to attach to the chips. You can find instructions for replacing those here. For newer Obelisk miners that used thermal paste to secure and help disburse heat, they can be easily repaired by you or your colocation facility. Remove the heat sink (or leave it off if it fell of) Scrape the remaining hardened thermal paste off with a smooth, flat device similar to the ones found here. Reapply the thermal paste. Typical application involves a pea-sized or smaller dot on the center of the chip, and then firmly but gently putting the heat sink back on. This will re-attach the heat sink to the chip, allowing it to properly dissipate heat.

5. The Ultimate Guide to Your Heat Pump

Even in cold temperatures, heat still exists in the air. The heat pump refrigerant absorbs the heat from the outside air, compresses it making it even hotter and sends it to the coil. The coil heats up from the heated refrigerant passing through it and conditions the air as it is blown across the coil. As the passing air grabs the heat from the coil, the refrigerant inside the coil cools down and is sent back to the heat pump to absorb the heat from the outside and repeats the process. As the temperature outside drops, it is harder for the heat pump to extract enough heat to keep up with the homes heating needs. When the heat pump cannot keep up the the homes heating needs, it has reached its "Balance Point" and needs back-up heat sources, such as resistant heat strips to keep the home comfortable.

6. what do i do when my dog goes into heat?

Buy a doggie diaper that's made of cloth or denim (can be found at any local pet product store) and purchase the pad-like inserts that go in. If you think she's going to go into heat soon, and it's going to be her first heat, do not count on her to keep herself completely clean all the time. I just have my dog wear hers when she's in the house so she does not get a mess on the furniture, etc. But you can take it off when she goes outside to potty. That's the best advice I can give. You chihuahua male should not get aggressive when she's in heat. Good luck!
