Understanding static pressure in fans
Understanding static pressure in fans
(OP)
This may be a trivial question to those in the industry, but, can anyone help me understand the concept of static pressure in terms of fan design and operation. From some works I've read they make it seem like something present in the environment (ie atmospheric press), and some describe it more as something produced by the fan. As say a customer sitting under a ceiling fan I know what "more air" feels like, but is this just faster moving air, or air moving at higher pressure?
Thanks
Thanks

so faster moving air has lower static pressure, and the experimental subject sitting under the ceiling fan is feeling the higher dynamic pressue (faster moving air, applies more force to a object (the subject) standing in the airflow)

the fan does useful work on the air, by giving it a velocity, increasing the total pressure. ceiling fans don't have much power, so they don't create a hurricane, but more like a gentle breeze.
