Abstract:
While transporting liquid in pipes, energy loss due to friction between pipe wall and liquid molecules all through the pipe and also with the sudden change in flow direction which happen because different fluid tools such as elbows and vulves.
This work deals with finding coefficient of energy losses for PPR pipes locally manufactured and adopted by the design of the experimentally form which has two branches A , B.
Branch A consist of 16 elbows and was intended to account minor losses, and the value which was obtained is K=29.32 .
Branch B consist of 16 elbows and 8.5 meter from the length of the pipe in order to obtain the experimental friction factor k=.03
. B was intended to get the major losses to the length of the pipe using the values of branch A
The experimental friction factor has been used to find the pipe roughness which equal =0.004 .This roughness has been confirmed using the equations from the references.
