KAJI EKSPERIMENTAL KOEFISIEN KERUGIAN PADA PERCABANGAN PIPA DENGAN SUDUT 45 DERAJAT, 60 DERAJAT DAN 90 DERAJAT

Abstract: During  fluid  flow  through  the  system  piping  installation  happened  many  so-called  pressure loss as the major pressure loss and minor pressure loss (loss due to fluid passing through  a branching).  Distribution  of  the  fluid  flow  in  branching  is  an  irreversible  process.  This irreversibelitas  in  the  application  techniques  will  reduce  the  performance  of  a  system. Attemps  to  find  out  how  big  the  losses  incurred  by  branching  pipe  is  to  measure  the coefficient of losses incurred. The form of experiments performed was to make three pieces of pipe brnching angles galvanic type medium with 450, 600and 900. Re variation of 0 to 5,5 x 104. The results showed that the coefficient Of loss for k3-2 branch (45)= k3-2 (60)= K3-2 (90)=  (0,07  to  0,39)  and  k3-1  branch  (45)=  (0,95-  0,60),  K3-1  (60)=  (1,08  to  0,85),  K3-1 (90)= (1,10- 1,50), for a total coefficint Ktot (45)= (1,02 to 0,97), Ktot (60)= (1,15 to 1,23), Ktot (90)= (1,17 to 1,89).
