METERING OF LOCAL IMPEDANCE AT HYDRAULIC CALCULATION OF INNER WATER SUPPLY NETWORK OF BUILDING
The paper deals with the problems of hydraulic calculation of the inner water supply network of a building, in particularly, the determination and metering of local network impedance such as a water meter, a screen filter, a nonreturn valve consisting an apartment water metering post. The need for metering at the hydraulic calculation of necessary head not only for local impedance of a water metering but also of a screen filter and a nonreturn valve has been valid in the paper.
