Adiutori efadiutori@aol.com 1 Ventuno Press, 1094 Sixth Lane N., Naples, FL 34102 The purpose of engineering laws is to describe parametric behavior. Experiments indicate that h is a constant or a variable. The law of convection heat transfer cannot be q = hΔT because it states that h is always a constant. Since sometime near the beginning of the 20th century, the equation q = h{ΔT}ΔT has been the de facto law of convection heat transfer because it states that h is a constant or a variable. q = h{ΔT}ΔT is NOT dimensionally homogeneous if h is a variable because the dimension of q is not equal to the dimension of h{ΔT}ΔT. q = hΔT is not acceptable because it states that h is always a constant. q = h{ΔT}ΔT is not acceptable because it is not dimensionally homogeneous if h is a variable. A new law is required that always describes behavior, and is always dimensionally homogeneous. http://pubs.sciepub.com/ajme/11/4/3/ajme-11-4-3.pdf Convection heat transfer de facto law of convection heat transfer Fourier law of convection heat transfer nonlinear heat transfer behavior
