ABSTRACT Abstract
Piping junction is frequently applied in piping system for industries, mining, and drinking water distribution.Different types and Piping Junction is frequently applied in piping systems for industries, mining, and drinking water distribution.Different types and
angles in the junction produce different stream distribution. angles in the Junction produce different stream distribution. Analysis and computation will establish certain influence on Analysis and computation will establish certain influence on
piping junction angle towards flow distribution as well as developing it for other condition. Junction angle towards piping flow distribution as well as for other developing it condition.
Analysis of distribution in type-T junction for stream separating two horizontal dimension uses CFD (Computational Fluid Analysis of distribution in T-type Junction for stream separating two horizontal dimension uses CFD (Computational Fluid

convergence test with the thickness 0.15 meter. Convergence test with a 0:15 thickness meter. Initial and boundary condition are determined based on the problem. Boundary and initial condition are determined based on the problem.
The study shows that changes in junction inlet debit from Reynolds number Re+1=000 up tp Re=6000 will increase the flow The study shows that changes in Junction Inlet debit from +1 Reynolds number Re = 000 Re = up tp 6000 will increase the flow

The study shows that changes in junction inlet debit from Reynolds number Re+1=000 up tp Re=6000 will increase the flow
