[SOLVED] SCAF Solar City Air Filter (help!)

Hi people,
I am working on a this project, SCAF. It's a 3 part tower made of glass with filters around the short upright bottom section, the middle section is of laminated glass and slopes up to the top narrow vertical chimney section. PV panels are plaxed around the sunny side of the chimney section and a small wind turbine inside the chimney. The goal of the project is to use the suns energy to simultaneously filter the air of a city and produce green energy.

What I want to know is if I treat it as a closed system what is the formula to work out pressure difference caused by heat increase? ie 10psi per degree C increase or whatever. Or as it is an open semi-open system is there a formula or chart that shows the pressure difference between the inside and outside at various temperature differences? How can I work this out?
In your answer please take into account that I have never taken or studied physics.

This project uses the same principle but on a large scale.

Thanks for any help you guys can give me. If you want more info on the project and it's status,(first prototype is under construction), check the attachment, unfortunately I haven't translated it so some is in french, well I think I uploaded a file if not let me know.

Unfortunately, the answer to your question is not so simple. Since the SCAF system is an open system, you cannot really calculate the pressure difference caused by a temperature increase using a single formula. Instead, you will need to take into account factors such as the air density, the size of the system, the venting characteristics, and the shape of the filter material. In addition, you will also need to consider the various components of the system and how they interact with each other. In order to properly calculate the pressure difference, it is best to use computer simulation software, such as Computational Fluid Dynamics (CFD) software. CFD software is designed to simulate the behavior of fluids and solids in complex systems like the SCAF system. This type of software is commonly used for engineering applications, and it can help you to accurately predict the pressure differences between the inside and outside of the system, at various temperatures. Alternatively, if you are not comfortable with using CFD software, you could consult an expert in engineering or thermodynamics who could help you develop a mathematical model of the system, which could then be used to calculate the pressure differences. Good luck!

Hi CJ,

Thank you for reaching out for help with your SCAF Solar City Air Filter project. It sounds like a very innovative and environmentally-friendly idea. I'm not a physics expert, but I can provide some general information and resources that may help you with your question.

Firstly, in order to calculate the pressure difference caused by heat increase, you will need to know the volume and temperature of the air inside the system. From there, you can use the ideal gas law (PV=nRT) to calculate the pressure difference. This formula takes into account the volume (V), pressure (P), number of moles (n), gas constant (R), and temperature (T) of the gas.

As for the pressure difference between the inside and outside at various temperature differences, this will depend on a variety of factors such as the size and design of your system, the amount of air flow, and the external temperature. It may be helpful to consult with a physics expert or use computer simulations to determine this information.

In terms of resources, I suggest looking into thermodynamics and heat transfer principles. These concepts will help you understand how heat and pressure are related in a closed system. You can also search for online calculators or tools that can help you with your specific calculations.

I also recommend checking out the project you mentioned, Enviromission, as they have already successfully implemented a similar concept on a large scale. You may be able to find more information and resources through their website or by reaching out to them directly.

Best of luck with your project and I hope this information helps. Let me know if you have any other questions or need further assistance. Keep up the great work!
