Měření součinitele tření při proudění vody v trubkách různých materiálů

Abstract

The content of this thesis is measurement of the frictional coefficient in water flow in the pipes of different materials. The theoretical part deals with the issue of real liquid flow and characteristic of frictional coefficient. There are cited formulas for determining the friction coefficient according to different authors. The theoretical part also deals with the weir issue and their characteristic. The practical part contents design, assembly and practical measuring on the measuring track. There are listed description of a measuring track and process of measuring. For illustration, the measured and calculated values are converted into graphical form.
