摘要：

Expressions for the factor K to relate the total frictional head loss, average outlet operating pressure head, and the inlet pressure head of a multioutlet pipeline are developed. In the developed expressions, the factor K is a function of the number of outlets on different pipe diameters, combination of diameters, and position of the first outlet from the inlet. Values of the factor K obtained from the developed expressions are compared with constant values being taken as per existing practice. The comparison suggests using the developed expressions for accurate computation of the factor K for multioutlet pipelines especially comprising of two or more diameters. An example is presented to compute the inlet pressure head of a multioutlet pipeline using the factor K.
