Seeking Appropriate Equation for Linear Conductivity

  1. Oct 28, 2009 #1
    1. The problem statement, all variables and given/known data

    I am attempting to calculate the approximate time it takes for a stone slab to fully preheat, focusing only on one dimensional steady flow conduction. Both my area and mass are unknown.

    Thermal conductivity: 6.4 W/mK
    Specific heat capacity: 0.98 J/gK
    Density: 2,980 kg/m³

    Thickness of slab: 3.18 cm
    Distance to center: 1.59 cm
    T1: 260 C.
    T2 (core): 21.11 C.

    2. Relevant equations

    This is what I'm looking for.

    3. The attempt at a solution

    I've spent hours looking through textbooks trying to find the right equation, but everything I run across seems to have additional info such as area and mass.

    You will have to give us the whole problem. Area and mass are needed but I suspect that they fall out in your calculation.
