Fisica Tecnica 1 module addresses the specific topics of thermodynamics and heat transfer. Starting from the first and second law of thermodynamics, which regulate energy exchanges between a system and what surrounds it, and considering the thermodynamic properties of simple fluids, the course gets to the description of sequences of thermodynamic transformations, which allow us to evaluate the performance of direct cycles and refrigeration cycles. Furthermore, the module deals with the basics of physical phenomena that determine the heat transfer between bodies, fluids and surfaces.
Provide the basic knowledge related to applied thermodynamics , the heat transfer , fluid dynamics and thermodynamic principles of environmental conditioning .
The student should acquire the capability of: resolving simple energy balance for closed systems and control volumes, at steady state conditions; evaluating thermodynamic and thermal properties of simple fluids, such as perfect gasses or homogeneous liquids; describing the basic energy conversion processes; calculating heat flux and heat flow rate in simple geometries and calculating pressure drop in pipes.

APPLIED PHYSICS 1
The exam consists of a written test and an oral test that take place on different days, to access the oral test it is necessary to have passed the written test with a positive result. The written test can be replaced by two partial tests, carried out during the lesson period.
The written test verifies the student's ability to solve problems in Technical Physics and Heat Transfer. It is a threshold to access the oral exam.
The oral exam is aimed at ascertaining the learning of the theoretical bases, presented during the course. The evaluation of the student is carried out during the oral exam and it is based on the ability to describe autonomously, with coherence and properties of terms, the topics and demonstrations presented in class.
