Application of the C Language Programming in Measuring Liquid Viscosity by Ball-Dropping Method

In the age of big data,in order to improve the processing efficiency in physical experiment,reduce artificial errors in data processing,this paper discusses the experiment of measuring liquid viscous resistance coefficient based on the Ball-Dropping method. Using efficient,structured and modular programming language and process-oriented programming technology,a C language program is written to apply to the liquid viscous re-sistance coefficient measuring experiment,and to calculate the relative uncertainty of the viscous resistance co-efficient according to the related theory,which further expounds the feasibility,superiority,generalizability and applicability of the C programming language in data processing of physical experiment,and brings up a high-ef-ficiency physics experiment data processing method combining the use of Excel and C programming language.
