The course is given during fall semester, 2nd period. The course includes lectures (32 h), exercises (32 h) and four laboratory sessions and three quizzes and an examination. The lectures present the general ideas and theoretical explanations behind heat transfer. In the exercises the theory is applied for different heat transfer problems.
