How to calculate heat transfer over time?

The heat transfer formula through conduction is given by: Q/t = kA((T1-T2)/l), where Q/t is the rate of heat transfer, k is the thermal conductivity of the material, A is the cross-sectional area, T1-T2 is the temperature difference, and l is the thickness.

How do you calculate borehole thermal resistance?

For this heat transfer, a local borehole thermal resistance can be defined: R b = T f , l - T b q b where T

_{f}_{,}_{l}is the local mean fluid temperature (K), T_{b}is the borehole mean wall temperature (K), q_{b}is the heat transfer rate (from the borehole to the ground) per unit length (W/m).An Analytical Method to Calculate Borehole Fluid Temperatures for Time-scales from Minutes to Decades.
