Is there a way to calculate how warm air will get when it passes a source of heat knowing how fast the air is moving?
For example, let's say there is an object being heated by 40W of electricity and there is a fan blowing 20C air past the object at 30 cubit feet per minute. Assuming a perfect setup where there is no air leakage and it's purely air in and air out is there a way to calculate this? I'm thinking we might also need to know the surface area of the heated object and if that's the case is it possible to assume it's large enough to perfectly transfer all heat into the air, or if that's not possible I can estimate the surface area to be 0.2 meters squared. Also all surfaces are metal in case that matters.
