Learning activities and teaching methods
Monologic (reading, lecture, briefing), Work with text (with textbook, with book)
Learning outcomes
The aim of the subject is to explain theoretical fundamentals of the fluid flow and heat transfer. The phenomenological approach is based on solving of differential and integral balances of momentum and energy. The individual topics involve formulation of the basic equations of flow and heat transfer, inviscid fluid flow, laminar and turbulent flows of viscous fluids, description of hydrodynamic and thermal boundary layers, heat conduction, convectional heat transfer, and analogy between momentum and heat transfer.
After passing out the subject, the student is able to solve the basic problems of the fluid flow and heat transfer in the design and check calculations of industrial apparatus. He is able to study the special literature dealing with the fluid flow and transfer phenomena.
Prerequisites
Mathematics I and II, Chemical engineering I

Assessment methods and criteria
Oral examination, Written examination

In the written part of examination, which serves to the verification of student application abilities, the student solves three characteristic practical problems of the fluid flow and heat transfer. The basic form of the oral examination is a discussion about two given areas. The degree of the acquired knowledge is examined.
