摘要
依据泊肃叶定律给出的描述液体粘滞系数的公式,自行设计实验装置,测量出有关量,计算液体粘滞系数并与理论值进行比较。实验结果能较好地反映粘滞系数与液体温度关系的变化趋势。
Based on the equation of the liquid viscosity coefficient described by the Poiseuille＇ s law, the liquid viscosity coefficients were calculated with some parameters that are measured by a self-made equipment in laboratory. Compared with the theoretical values of the liquid viscosity coefficient, the measured coefficients agree with the theory well. The experiments show that the variation of the viscosity coefficient is related to the liquid temperature.
