- Element 1
Explain and apply the first law of thermodynamics to mechanical engineering.
Performance criteria
1.1The first law of thermodynamics is explained in terms of the conservation of energy and the flow energy equation.
1.2The first law of thermodynamics is applied to the solution of flow and non-flow processes.
1.3The production of energy from natural and renewable sources is explained in terms of mechanical engineering concepts and the factors influencing energy production.
1.4Energetics of work are explained in terms of the way energy is exchanged and its influence on the states of matter.
1.5Calculations are made of heat transference via conduction, convection, and radiation.
1.6Heat and heat capacity are explained in terms of the affects of heat energy moving between bodies of different temperatures.
1.7Calculations involving heat capacity are made to determine the amount of heat required to raise and lower the temperature of a substance by 1 degree K.
1.8Changes of state are explained in terms of internal energy, enthalpy and the changes in heat, work, temperature, and pressure.
1.9Calculations are made of the change in volume of a solid or liquid if the pressure or temperature is increased.
1.10Calculations are made of the change in volume of a gas if the pressure or temperature is increased.
1.11Phase changes are explained in terms of their consumption or liberation of energy.
Rangemay include one or more of the following - fusion (melting), freezing, vaporization, condensation, sublimation.
1.12Calculations are made of the amount of flow and/or energy required to achieve a change in an energy phase.
Element 2
Explain and apply the second law of thermodynamics to mechanical engineering.
Performance criteria
2.1The second law of thermodynamics is explained in terms of reversibility, entropy, and the relationship between changes in volume and energy.
2.2A model heat cycle is explained in terms of expansion and compression.
2.3The efficiency of a heat engine is calculated. - Basic of Assessment
