Fluid Mechanics Part II

The purpose of this course is to enable students to analyze, understand and solve technical problems in aerodynamics, hydrodynamics and hydraulics that occur in engineering applications. Students are provided with the appropriate theoretical knowledge and they are encouraged to develop the skills needed for measuring various flow quantities of importance. For this purpose, in addition to a lectures series for the development of a theoretical background, a group of related laboratory exercises are conducted in order to train students to use properly various measuring instruments and devices, as well as to assess correctly the measurement data.

Objectives

Upon successful completion of this course the student will be able to: • understands the basic principles and laws governing the flow of fluids in specific cases. • Distinguishes explains and resolves technical issues arising from the use of fluids in various technological applications. • It uses measuring devices to record Flow field size and properly utilize the measuring data.
