Thermodynamics in Mechanical Engineering

Why to go through the concepts of Thermodynamics? Different mechanical processes all around us answers it such as refrigeration process, mechanical engines, power plants work or properly defined chemical reactions. This workshop will provide theoretical fundamentals of thermodynamics, particularly the energy conversions heat to work and work to heat are discussed. This course lays the groundwork for subsequent studies in fields such as fluid mechanics, heat transfer and statistical thermodynamics, and prepares readers to effectively apply thermodynamics in the practice of engineering.
