Essay

The theses is dedicated to the problem of fluid dynamics flow parameters determination in pressure distributing piping of water supply and water disposal systems and based on it to the elaboration of new more reliable methods of calculation. On the basis of the fulfilled review of the researches dedicated to the flow in distributing piping, basic regularities of such tendencies were generalized and analyzed. A considerable extent of experimental data was received and analyzed. Flow kinematics and the reasons of the increasing of the pressure loss in distributing piping in comparison with the pipes with entire walls were determined. Empiric formulas for the determination of the hydraulics constant of friction , the coefficient of expenses and the coefficient of the excreted mass were cited. On the basis of the received analytic and experimental data more generalized and reliable method of the engineering calculation in distributing piping has been worked out.
