Determinación del flujo inicial de calor de la superficie interna de un horno aplicando la segunda ley de la termodinámica

Abstract

The second law of thermodynamics states that heat can only flow from a hot body to a cold body, only if there is a temperature difference, under this principle the statement has been developed. The objective of this work is to determine the initial speeds of heat flow in each internal surface presented in an oven, under conditions and parameters established in the case. The area of each of the plates was determined and the temperature was converted to Rankine degrees. By applying the Second Law of Thermodynamics, and by means of the radiation equation to a surrounding object, the initial heat transfer rates of each internal surface could be determined. The English system has been the system of units used. The results obtained: q_A1=280113.71, q_A3=560227.42 , q_A5=2147887.057 , q_A6=752879.27 expressed in btu/h, each of these values being the heat loss flux of each plate in relation to the water in the pipe, with area 5 being the highest initial heat loss flux.
