Fluid flow resistance test as one of the common problems, the experimental data processing is cumbersome and complicated, and manual processing of data causes more trouble and greater error, so it is difficult to achieve a better experimental teaching purpose. MATLAB is a high-performance scientific computing language, with the features of numerical calculation and visualization in one, simple and flexible language, numerical stability, and rich internal functions. In this paper, the experimental study of fluid flow resistance is taken as an example, the efficiency and practicability of numerical calculation of the MATLAB and its powerful operation and graphical representation in chemical engineering experiment are briefly described.
