Heat transfer rate

If the thermal conductivity of the material through which heat is transferred is decreased by a factor of 1 then the rate of heat transfer is decreased by a factor of 10. T: difference in temperature between the solid surface and surrounding fluid area, K. It is used in calculating the heat transfer , typically by convection or phase transition between a fluid and a solid. This article needs additional citations for verification.
