The cooling ability of liquid increases with rise of the flow rate. In this report, the relation among the cooling ability, the flow rate of oil in turbulent streams and the diameter of specimens were examined and the next equation was obtained:<BR>(This article is not displayable. Please see full text pdf.) <BR>\oindentwhere H and H0 are the severity of quench in the cases of flowing state and still state of oil, D the diameter of specimen, Re the Reynold’s No., (vD⁄ν) and Pr the Prandtl’s No., (cρν⁄λ). K, m and n are constants. V is the flow rate and ν the kinetic viscosity of oil. λ, c, and ρ the thermal conductivity, the specific heat and the specific gravity of oil respectively. This relationship quantitatively determines the effect of flaw rate on the cooling ability of oil and give basal data to design a quenching tank and its agitating device.
