How Does Induction Heating Work and What Factors Affect Its Efficiency?

AI Thread Summary
Induction heating efficiency can vary based on the power available, such as 8800 Watts or 220V at 40 Amps, and the specific characteristics of the iron object being heated, including its size, shape, and thickness. The depth of heat penetration and the time required to reach desired temperatures are critical factors, particularly for geometries like a 1/4-inch iron pipe. Using RF coils in the range of 20-100 kHz may effectively heat materials like copper pipes. For precise calculations and efficiency insights, consulting an induction heating company is recommended. Understanding these variables is essential for optimizing the heating process.

What is the efficiency of induction heating? What if you only had 8800 Watts available, or perhaps 220V, 40Amp... what size iron object could you heat, and to what temperature? Size will have to be qualified... how long? What shape & how thick? Depth of heat penetration. Then how long would it take to heat this object. Now what if this was an iron pipe, let's say 1/4inch... then we passed water through it? Sorry, but I have a lot to learn...

I assume you are interested in a pipe geometry, and not a flat plate. There are RF stoves that heat pots and pans with copper bottoms. I suspect that an RF coil (20 - 100 kHz) in the form of a solenoid could heat a copper pipe. I would contact an induction heating company like:

They could give you information on heating efficiency.

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
