The formula of static pressure distribution parameters of distributing headers was obtained on basis of the analysis of the momentum conservation equations of micro-control volume in distribution headers, the correlation of static pressure distribution parameter with the momentum exchange coefficient and the definition formula of the momentum exchange coefficient and the formula of straight pipe's local resistance coefficient in three-way pipe. The influences of size and distance from the entrance of the distributing header for static pressure parameters are included in this formula. The calculation results well agree with the experimental results. The calculation of the hydrostatic pressure distribution along the length of distributing header can be done conveniently and accurately by using this formula.
