| Abstract: | By solving the incurvate vibrating equation,it is obtained the solution of the dynamic equation with flowing liquid inside the tube.The main forces on the liquid particle and the relationship between the loss energy and the power caused by exterior forces are analyzed,and the formula to solve the relationship among loss energy,flow velocity and viscosity are derived.Also the effect of the velocity on the measurement of fluid viscosity is analyzed,and the correctness of the conclusion is proved by experiment... |
