摘要
在流体力学实验教学过程中发现,文丘里实验由于测量误差和系统误差,导致实验结果往往与公认值有很大差异,文章围绕可能出现的误差进行了分析,经过多次精细实验讨论文丘里不同倾角对实验精度的影响。以创新型、综合型实验设计为目标,通过对流体力学文丘里实验精度的测试与改进方法的研究,改进提高测量精度,成果可以直接应用于教学。
In the teaching process of fluid mechanics experiment,it is found that the experimental results of Venturi experiment are often quite different from the recognized values due to measurement errors and system errors.This paper analyzes the possible errors and discusses the influence of different angles of Venturi on the experimental accuracy through many fine experiments.With innovative and comprehensive experimental design as the goal,through the research on the accuracy test and improvement method of the fluid mechanics Venturi experiment,the measurement accuracy can be improved and improved,and the results can be directly applied to teaching.
