Rules for evaluation and completion of the course
Since it is not obligatory for studentsn to be present at lectures, the presence will not be checked.
Aims
Students will learn how to define tasks, boundary and initial conditions and correct physical parameters. They will learn how to employ dimensionless analysis. They will be able to solve real problems like cooling fuel elements, finned tubes and/or cylinders of internal combustion engines, cooling turbine blades, calculate flow rate of condensing liquid, heating by radiation in rooms, etc.
