### Wind Tunnel properties based on different stations in flow simulation

From stations 1 to 10, there is a minimal difference between Mach number, pressure, temperature, and density. The parameters are almost the same. From stations 11 to 16, there are greater discrepancies between the data values from theoretical equations and flow simulation results in terms of the pressure, temperature, density, and most notably in the values of Mach number at each station. Whereas the data values from the theoretical equations are higher than what we got from the flow simulations.

### The importance of computing flow properties in the wind tunnel

Computing flow properties in the wind tunnel using flow simulation is important because it allows users to run complex simulations that are hard to do or solve manually. The ability to run these simulations automatically means that the user does not have to spend time solving the parameters manually, which saves time and effort. It can also lead to increased accuracy in results and a reduction in the number of errors.

Computing flow properties in the wind tunnel using theoretical equations is important because it allows us to design more efficient products and systems. When we understand how air flows, we can ensure that the products we create are as effective as possible. In our experiment, we first use the theoretical equations before designing the wind tunnel and conducting the flow simulation. We believe that using theoretical equations is the fundamental of engineering design.

Overall, Computing flow properties in the wind tunnel using flow simulation and theoretical equations is important because it can help engineers to identify and understand what is happening to the fluid as it moves through the system. This information is then used to make decisions about the experiment, such as which tests should be performed or what adjustments should be made.

In conclusion, the only noticeable discrepancies of parameters are seen from the result of theoretical equations and flow simulation in stations 11 to 16. It shows that higher values are shown on theoretical equations.

Despite their differences, these two aid the engineers in identifying and understanding how the fluid acts as it moves through the system. Wherein, using flow simulation helps an engineer to run complex simulations which are difficult to solve manually, meanwhile using theoretical equations helps in designing more efficient products or systems. The results acquired from these two can help the engineer to decide on what will be the next procedure and on what changes should be made in order to achieve its desired results.
