3. Supporting WEB network version of the Fluid Mechanics Cloud Platform experimental data processing software: Configure the cloud platform experimental data processing software to scan the QR code tag. Scan the mobile browser to directly open the experimental data processing cloud platform, input the experimental data recording table, automatically calculate the experimental calculation value table, and display the experimental data analysis curve graph. At the same time, it has the functions of saving experimental records, reading and deleting historical records. When the computer is opened, it also has the function of printing and outputting all experimental data tables and curve graphs, which conforms to the experimental report in the experimental textbook;

4. Supporting WEB network version experimental virtual simulation CAI software

(1) No need to download the app, you can directly access the internet through client computers or browsers such as iPads and tablets. After logging into the virtual simulation CAI website cloud platform for fluid mechanics experiments, you can operate the simulation experiment and have the user security management function of using username and password login interface;

(2) The experimental interactive operation includes simulation of any switch with 4 valves and simulation of the inflation and pressurization device, and the interactive animation interface of inflation and pressurization, deflation and drainage, and pressure reduction is lifelike;

(3) The liquid level changes of pressure measuring tubes, connecting tubes, and vacuum negative pressure tubes can be dynamically displayed in the form of animations through user interaction with various valves and balloons, and the simulation effect of liquid level changes is consistent with the real prototype;

(4) Having error prompts and experimental status prompts for experimental operations, it can train students on the correct steps and methods for real experiments. It has real user experimental interaction operations, not video demonstrations, and can simulate experimental data changes and animation feedback in real time based on user interaction;

(5) By combining valves and pumping devices, different static water pressure data of the pressure measuring tube can be simulated and measured when the upper air pressure inside the static water bucket is greater than the external atmospheric pressure, equal to atmospheric pressure, and less than atmospheric pressure; Further simulation can be conducted to display non constant current and constant current states, record the head data of the pressure measuring tube under different flow states, and then analyze the results;

(6) Through the interactive operation of inflating and pressurizing, deflating and draining, and reducing pressure, as well as the combined measurement of static water pressure measuring tubes, the bulk density of oil placed on the U-shaped pressure measuring tube can be simulated and measured. By recording experimental data from two sets of measurements, the bulk density of oil can be calculated in the results analysis table.
