| Abstract: | 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. |
