Summary
In this course students learn the basic principles of two disciplines: fluid mechanics and thermodynamics.
Fluid mechanics deals with the balance of forces in liquids at rest and in motion.
Basic laws of mechanics are applied, i.e. the conditions of force balance and momentum balance, conservation of mass and energy.
Thermomechanics is a basic science, which includes thermodynamics of gases and heat transfer. It has a number of practical applications in various disciplines and in everyday life.
Learning Outcomes of the Course Unit
In this course students learn the basic principles of two disciplines: fluid mechanics and thermodynamics. They will be based on knowledge gained in general mechanics, which can be applied to discover the laws of the continuum. To understand the curriculum they implement a simple experimental task. They will be able to solve practical problems of thermodynamics and fluid mechanics and will get familiar with solving complex engineering problems.
