Problems solved by technology
[0002] At present, the traditional fluid mechanics experimental teaching equipment has the following problems: 1) The function is single, and one experimental device can only complete one fluid mechanics experiment, and each experiment requires a lot of preparation work, which is inefficient; 2) During the experiment, the pressure Traditional pressure tubes and Pitot tubes are mostly used for the measurement of flow rate and flow rate, so the reading time of measured data is long and the accuracy is low; 3) During the experiment, all test data need to be handwritten and recorded in time, and then calculated after the operation is completed Comparison, and various valves need to be manually opened and closed or manually adjusted opening during the experiment, the degree of automation is low
