2.) On a windy day, the same logic applies. The wind passing over an open, unobstructed hole in the roof would result in lower pressure outside the roof hole. Air inside the attic would move to lower pressure through the hole. With a turbine, the wind spins the turbine fan but that does not result in lower pressure.
Computer engineering or Computer Science engineering integrates several disciplines such as Information Technology, Electrical and Electronics Engineering, Software Design, etc. The engineers are mainly involved in the development of software and hardware systems of various aspects of computing.
Computational science and engineering (CSE) is a relatively new discipline that deals with the development and application of computational models and simulations, often coupled with high-performance computing, to solve complex physical problems arising in engineering analysis and design (computational engineering) as well as natural phenomena (computational science).
