EFFECT OF SMALL AMOUNTS OF POLYISOBUTYLENE ON TURBULENT FLOW OF KEROSINE IN A TUBE
Kerosine solutions containing 0.05% polyisobutylene were passed through a copper tube of 11 cm dia under turbulent flow conditions. The frictional resistance to flow decreased linearly with the log of Reynolds number. Flow resistance decreased even at a Reynolds number of 8000. At a Reynolds number of 40,000, the flow resistance of polyisobutylene solution was 18% below that of pure kerosine. With repeated criculation of the polyisobutylene solution through the pump, flow resistance increased, signifying that degradation of polyisobutylene occurred. Greatest friction reduction was obtained with polymers whose molecular weight exceeded 2 million.
