Abstract
Elbow 90o or curved pipe having radius is often used in engineering field especially in fluid piping system. At high Reynolds number or for turbulent flow, the radius of elbow effect the fluid varibles. The elbow having small radius of carvature make higher pressure drop between entrance and exit section of elbow when it is compared to the elbow having higher radius. This high pressure drop makes the loss coefficient of energy higher than that of the elbow having larger radius. The debit of flow increase linierly as the increase of radius. The cross section of elbow ; that are circular and rectanguer, influence to loss coefficient and debit. Both cross section of pipe have similar profile of loss coefficient which decrease rapidly with relatif radius and similar profile of debit
