FIELD: machine building.
SUBSTANCE: proposed method comprises measuring pressure difference at actual length of pipeline without anti-turbulence additive in pumped fluid, adding said additive of different concentration till pipeline length filling, measuring pressure difference after every filling and calculating additive efficiency for every concentration by the following formula: φ(Ci)=(ΔP0-ΔPCi)/(ΔP0-ΔP”гст”). Note here that flow rate of pumped fluid is kept equal to that without additive by measures not affecting resistance head in tested pipeline length during adding said additive and measuring pressure difference.
EFFECT: higher accuracy of determination.
