Summary
The subject acquaints students with energy consumption during development of human civilization, types of energies, sources and physical laws of energy transformation. Students will learn the properties of gaseous fuels, issues of interchangeability of heating gases, fuel pricing, normalization of energy consumption and approaches to the generation of energy and exergetic balances. They will understand the problems of power machines and equipment for pumping water, compressed air production, steam equipment, cooling equipment etc.
Learning Outcomes of the Course Unit
Student will be able:
- categorize types of energy and energy sources,
- to distinguish gaseous fuels according to their properties, to evaluate fuels pricing, to assess the interchangeability of gases,
- determine the energy balance of equipment and normalize energy consumption,
- evaluate exergetic balances,
- characterize principles and choose suitable types of pumps, compressors,
- compare and evaluate the types of steam and gas turbine flows, cooling devices.
