# Heat conductance and temp measurement

1. The problem statement, all variables and given/known data

i'm trying to find out how to model a system consisting of a body at a finite temperature, connected to a heat conducting rod that is lagged (see scanned image) and a thermometer (or any other temp measurement device), what would i take into account while modelling this question? what would the model account for? and what is the best way to look at this thing?

2. Relevant equations
probably $\vec{q} = -k \nabla T$

3. The attempt at a solution

i would take into account the temperature gradient, Thermal conductivity (how is this modelled for an idealized conductor? i mean would k be 1 or what? ). if there's a book out there i need to see please let me know. it is not a coursework problem, so i'm free to look at it to the level best of my understanding.
