First, we want to help you develop an appreciation for the fundamental concepts and principles that underlie heat transfer processes. Second, we will illustrate the manner in which knowledge of heat transfer processes is used in conjunction with the first law of thermodynamics to solve problems in thermal systems engineering.
2. Fourier’s law of heat transfer: rate of heat transfer proportional to negative temperature gradient, Rate of heat transfer ∂u = −K0 (1) area ∂x where K0 is the thermal conductivity, units [K0] = MLT−3U−1 . In other words, heat is transferred from areas of high temp to low temp. 3. Conservation of energy.
