Dear Khalil

I agree totally with Dr. Yahia. The chimney air speed depends on many measures like: the electric power as Dr Yahia have mentioned, The size of the chimney for the receiver diameter  and the chimney height, the used wind turbines and so on. Also, the climate conditions are very important as the solar intensity increases in summer and reduces in winter as well as the outer air temperature. All these parameters must be specified to answer your question.

Good question!

It all depends on what electric power (MW) you want to get from the solar power chimney. For example, for a 100 MW system, tjhe hot air velocity should be about 16

meters per second. You can scale up or down this speed based on the MW you want to get.

Here is a nice article that you could read to learn more about this technology:
