摘要
利用毛细管法测定水的粘度,探讨了毛细管两端不同压强差对水粘度测量的影响。结果表明不同压强差对测量粘度有一定的影响,压差的减小使测量结果的误差增大,与理论相符。
According to the measurement of water viscosity by the method of capillary,investigating effects of measuring the liquid viscosity as pressure differences of Capillary two ends by the capillary method.The results showed that the viscosity of the liquid are effected by pressure differences,and the measuring errors of water viscosity increases with the decrease of pressure differences,the results match the theory very well.
