Equation for heat transfer rate

[icecool8]

Hi,

I am trying to create an apparatus to measure the thermal conductivity of woody pellet based on peltier effect. the fundamental equation for thermal conductivity is Q"=kA(Δt/Δl), where k is thermal conductivity. A is the area of pellet, Δt is measured by using thermocouple and peltier plate and length of the pellet is known. However, I am not too sure how to calculate the Q" based on the information that I have, Could anyone give me some tips to find the Q" by using other parameters? The one I was think of is using voltage & current from the power supply to calculate the resistance (R) through the pellet , and Q" =ΔT/R, Can I use this equation? Thanks

I am still awaiting for the reply from my supervisor from uni to verify my assumption, but at this stage, I don't have answer...
