Thermodynamics FIRST LAW OF THERMODYNAMICSFIRST LAW OF THERMODYNAMICSThe First Law of Thermodynamics is a balance of the various forms of energy asthey 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, ANALYZEan open system including all energy transfer processescrossing the boundaries.EO 1.21 Using the First Law of Thermodynamics, ANALYZEcyclic processes for a thermodynamic system.EO 1.22 Given a defined system, PERFORM energy balanceson all major components in the system.EO 1.23 Given a heat exchanger, PERFORM an energybalance across the two sides of the heat exchanger.EO 1.24 IDENTIFY the path(s) on a T-s diagram thatrepresents the thermodynamic processes occurring ina fluid system.FirstLawofThermodynamicsThe 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 controlboundary, external work and/or heat crossing the boundary, and the change of stored energywithin 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 exchangeof external work and/or heat complete the energy balance.Rev. 0 Page 53 HT-01
