ANALYSIS OF BEHAVIOUR OF T JUNCTIONS BY VARYING ANGLES AND TYPE OF FLOW.

T-junctions are one of the most difficult pipe fitting in terms of calculation of the head loss occurring through it. Various attempts have been made to derive the value of loss coefficients of the two branches of the tjunctions. Some formulas which involve area ratios and flow ratios are available. However, the use of these coefficients has to be further scrutinized. The erroneous effect of the use of constant loss co-efficients needed to understood and reviewed. This has been done, through the use of a standard network and the simplest network having one T-junction. Further efforts have been made to minimize the losses occurred at t-junctions and the implications of it in engineering design have been discussed
