If I have a typical Fan with a given CFM or even the outside diameter of the blade can I find the exIting temperature? Is there a formula out there to determine the exit temp. Assumptions: The fan is located in the middle of a room so we are not mixing in different temperatures. Given: CFM, Dia of the blade, Inlet Temp. Finding: Exit Temperature My thoughts. 1. Are my given conditions enough or will more factors be involved like pressure(atmpoheric[14.696 psi], etc.. 2. Common sense would think it would make the exit temp lower due to air being blow when a fan cools you down when standing next to it. Thanks.
