Thermodynamics (5 cr)

Evaluation scale

H-5

Content scheduling

The course takes place on Tuesdays and Fridays in weeks 36-50.

In the course, you get to know the phenomena of thermodynamics and practice related calculations and measurements from a physics perspective. Friday's classes are theory classes on the topic of the week. At the same time, things that remained unclear in the previous week's calculations are repeated. On Tuesdays, there is a calculation workshop (1h).

In addition to the theory lessons, the course includes two mandatory lab works, which are carried out in two different weeks (weeks 40 and 48) in small groups. Initial topics for lab work: Temperature dependence of the thermistor resistance, thermal conductivity and/or calorimetry.

Contents
- Basic quantities of thermophysics/thermodynamics, formulas, units, pressure, lift
- Thermodynamic system, temperature and thermal expansion
- Heat capacity, thermal energy and energy transfer
- Changes in state and energy in state changes
- Flows of liquids and gases, flow equations
- Liquid viscosity
- Equation of state of an ideal gas
- I and II law of thermodynamics
- Gas circulation processes
- Operating principle of heating and cooling machines
- Basics of moist air physics and the Mollier curve

Objective

The aim of the course is to familiarize students with the fundamentals of heat transfer and thermodynamics, thereby creating a basis for their application in the design and calculation of machines, equipment, and processes.
After completing the course, student:
- is familiar with the basic quantities of thermodynamics and can perform related calculations
- understands heat transfer and its effects in substances and structures (heat conduction , thermal expansion, phase changes)
- can calculate the heat quantity in various state changes
- can perform calculations related to the flow of liquids and gases
- knows the ideal gas equation and can apply it in various state change processes
- understands the state changes of ideal gases and the cycles based on them
- can determine the thermal efficiency of a heat engine as well as the coefficients of performance of a heat pump and a refrigeration machine
- can evaluate the energy efficiency of different machines
- is familiar with the Mollier diagram and its use in calculations related to heat transfer processes
- can investigate thermodynamic phenomena using measurement setups
