In order to improve the learning processes in terms of conduction of heat in a transient state, we present in this work the assembly and development of a team whose objective is to determine the coefficients of convection of water and air that cool two cylinders of different material which are copper and steel, these will be subjected to a free convection in the first place and then give way to forced convection, once obtained the data will be made graphs and tables, which will allow comparison of an experimental and theoretical values. In this way the students of the engineering faculty can have a physical experiment on the phenomenon that occur in the heat transfer given during the class, which will allow them to strengthen their knowledge.
