FIRST LAW OF THERMODYNAMICS

Thermodynamics FIRST LAW OF THERMODYNAMICS FIRST LAW OF THERMODYNAMICS The First Law of Thermodynamics is a balance of the various forms of energy as they pertain to the specified thermodynamic system (control volume) being studied. EO 1.19 STATE the First Law of Thermodynamics. EO 1.20 Using the First Law of Thermodynamics, ANALYZE an open system including all energy transfer processes crossing the boundaries. EO 1.21 Using the First Law of Thermodynamics, ANALYZE cyclic processes for a thermodynamic system. EO 1.22 Given a defined system, PERFORM energy balances on all major components in the system. EO 1.23 Given a heat exchanger, PERFORM an energy balance across the two sides of the heat exchanger. EO 1.24 IDENTIFY the path(s) on a T-s diagram that represents the thermodynamic processes occurring in a fluid system. First Law of Thermodynamics The First Law of Thermodynamics states: Energy can neither be created nor destroyed, only altered in form. For any system, energy transfer is associated with mass and energy crossing the control boundary, external work and/or heat crossing the boundary, and the change of stored energy within the control volume. The mass flow of fluid is associated with the kinetic, potential, internal, and "flow" energies that affect the overall energy balance of the system. The exchange of external work and/or heat complete the energy balance. Rev. 0 Page 53 HT-01
