PENGARUH VARIASI DIAMETER PIPA CABANG TERHADAP KOEFISIEN KERUGIAN PADA PEMISAHAN ALIRAN
ABSTRACT: The research aimed
to investigate: (1) the influence of flow rate ratio of loss coefficient (k) at
the branch pipe with angle 450, (2) the value of the local loss coefficient (k)
that occurs in the branch pipe diameter variations (branch) at, ½, ¾, 1, 1 ¼,
and 1 ½ inch, then straight pipe with a diameter 2 inches, and (3) the effect
of changing ratio between branch diameter pipe and a straight pipe to the loss
coefficient (k) on the pipe branch. The research was conducted with a form of
experiment, namely the dividing flow in a 45 Tee Junction with variation
diameter PVC pipe. After that it was calculated the local coefficient of losses
incurred by changes discharge ratio of 0.0 to 1. The results reveal that the
increasing of flow ratio with a variation branch pipe diameter increase the
total loss coefficient, Ktotal. Discharge ratio 0.0 to 1,the value of the local
loss coefficient from the main to the branch of K3-1 in ½ inch diameter branch
pipe 1.11 until 7.29, ¾ inch diameter 1.17 until 2.85, 1 inch diameter of 1.07
to 1.82, 1¼ inch diameter 1.08 until 1.40 and ½ inch diameter 1.02 to 0.92,
while the local loss coefficient related to the flow in the main of K3-2 range
from 0.04 until 0.48 for all variations of the branch pipe diameter. The
smaller ratio of the diameter of the branch pipes with the main pipe will
increase the value of the total losses coefficient.
