A hyperbolic boundary value problem of the thermal conduction of a two-dimensional plate with the third kind boundary conditions is formulated. The transient thermal process in the plate is due to the temperature changes of the external medium over time and along the plate length. and also by a multiple step change of the plate surface heat transfer coefficient throughout the transien... https://www.bekindtopets.com/flash-find-Mega-CMPK-Bolus-50-ct-limited-choice/
