Thermodynamics: 2 heatsources together and a heatsink

AI Thread Summary
The discussion focuses on creating a thermodynamic model involving two closely spaced heat sources, specifically cables carrying current, and a heatsink located 1.3 meters away. The main challenge is determining the temperature for calculating heat transfer (Q) due to the interaction between the two cables, which affects the temperature distribution. The goal is to establish the temperatures at a distance from each cable and the combined heat output from both. A steady-state model has been developed for a single cable, but the complexity increases with two cables in close proximity. The user seeks guidance on accurately modeling this scenario to account for the thermal effects of both heat sources.

I am going to create a model, with two heatsources closely spaced (Cables with a current) Covered with dirt and at a distance 1.3m from each cable there are a heatsink surround them.

My problem is when I am going to create the model, I am not sure at what temperature i need to calculate the heat Q, because the temperature between the cables must change because of the two cables, and that would effect the heat Q.

The goal is to know the temperatures at a distance R, from one cable and Q from both cables.

The model with to cables is steady state

And i have create a steady state model for 1 cable, but not with to closely spaced

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...
