                To study a calculating method for natural mix gas viscosity value and Reynolds number, a calculating example to known composition and average flow natural mix gas dynamic viscosity, kinematical viscosity and Reynolds number is provided. And the calculating error of viscosity and feasibility that take volume flow data method for Reynolds number calculating are analized. The man-machine interface realized by C + + Builder program is also given. The result of program operation shows the calculating result meets the requirements of natural gas flow state and measurement error analyze to the system.
