摘要
Results are presented of the measurement of the dynamic viscosity coefficient of heavy water at temperatures of 200-375 degree C and pressures up to 500 bar. Pressure differential over the capillary in an experimental apparatus was measured by a differential mercury manometer. Heavy water of 99. 98% concentration was used. Maximum relative error of values of the coefficient of dynamic viscosity was plus or minus 1%, maximum value of random error being plus or minus 0. 3%. Differences with previous, less accurate measurements are noted. An equation is worked out for the calculation of the viscosity of heavy water within the technically important region of densities 1. 5-2. 5.
