![]() ![]() Then put the atomizer or tank on the mod, and again make sure that it’s tightened down as far as possible (but don’t go crazy with over-tightening). In the case of rebuildables, make sure the leads are trapped firmly. Install the coil as normal but take care to ensure it is screwed down tightly, as far as it can be. The easiest way to achieve this is to not use the tank or the mod for at least five minutes before starting. After that, ensure that your mod and tank are both at room temperature so the temperature readings will be more accurate. If the mod has a TCR you can enter the exact TCR value. Put your mod into TC mode and select the corresponding wire type for the coils you have. To maintain a speed, more power is needed to go up a hill than down a hill… but the speed would stay the same. Think of it as a car traveling in cruise control. The resistance change is converted into a temperature increase and the mod adjusts its power to maintain the selected temperature. The mod checks the resistance of the coil at room temperature, then it continues to monitor it as you vape. That’s a particular property of Kanthal: its resistance is static regardless of its temperature.įor TC vaping, you’ll use wires that have a known resistance-increase as their temperature rises. When you vape with Kanthal (the most popular vape wire), that resistance value doesn’t change. You know there’s a coil inside your tank or atomizer that has a resistance, which-if you use any regulated mod-is shown on the screen generally with a “Ω” sign. As a vaper, you’re probably already familiar with resistance. But if you’re curious, TC works because the metal of certain coils predictably increases its resistance as it heats up. Separate calculations are thus required using Equation 1 for the material below and above the phase change temperature.You can use TC without ever knowing why or how it works. The Cp value (from Equation 1) of a material also changes with a change in state. ![]() How much energy is required to melt 50 lbs of lead?Ĭhanging state (melting and vaporizing) is a constant temperature process. Hv = Latent Heat of Vaporization (Btu/ lb ) Q D = Heat Required to Melt/Vaporize Materials Processed in Working Cycle ( Wh ) Q C = Heat Required to Melt/Vaporize Materials During Heat-Up ( Wh ) This same amount of energy is released as the vapor condenses back to a liquid. The latent heat of vaporization Hv of the substance is the energy required to change a substance from a liquid to a vapor. Another state change is involved in vaporization and condensation. The heat needed to melt a material is known as the latent heat of fusion and represented by Hf. Heat Required to Melt or Vaporize a Material In considering adding heat to a substance, it is also necessary to anticipate changes in state that might occur during this heating such as melting and vaporizing. ![]() How much heat energy is needed to change the temperature of 50 lbs of copper from 10☏ to 70☏? Heated media, work being processed, vessels, racks, belts, and ventilation air should be included. This equation should be applied to all materials absorbing heat in the application. ∆T = Temperature Rise of Material ( T Final – T Initial )(☏) ![]() Q B = Heat Required to Raise Temperature of Materials Processed in Working Cycle ( Wh ) Q A = Heat Required to Raise Temperature of Materials During Heat-Up ( Wh ) Since all calculations are in watts, an additional conversion of 3.412 Btu = 1 Wh is introduced yielding: Calling the amount of heat added Q, which will cause a change in temperature ∆T to a weight of substance W, at a specific heat of material Cp, then Q =w The specific heat capacity of a substance is the quantity of heat needed to raise the temperature of a unit quantity of the substance by one degree. Absorbed Energy, Heat Required to Raise the Temperature of a Material Because substances all heat differently, different amounts of heat are required in making a temperature change. ![]()
