Problem) External emission of carbon dioxide generated during power plant operation is environmentally harmful, so there is an absorption tower/regeneration tower device that removes it during the process. Carbon dioxide entering the absorption tower after power plant operation passes through the absorption towe r and is removed by dry absorbent grains present in the absorption tower, In general, since the process of absorblng carbon dioxde by an absorbent in an absor ption tower li an exothermic process, heat generated must be removed by passing cooling water through a tubular tube inside the absorption tower. However, t he absorbent grains hold the molsture present in the absorption tower, and as they come into contact with the surface of the cooling water tube in the absorpt! on tower, a reaction called sticking occurs in which the absorbent adheres to the outside of the tube. Since the heat exchange between the heat transfer plpe an d the regeneration tower does not occur smoothly due to sticking it is important to determine the degree of sticking and remove it. Problem: Since the heat transfer coefficlent (thermal conductivity, k ) of the adhering absorbent cannot be predicted directly, an equation for the heat transfer c oefficlent that can be calculated by measuring T1 and T3 in Experiment 1 and T1 and T3 in Experiment 2 is needed. Define the dural modulus and surface area in alf, etc, and derlve the formula
