Calculating Required Area for Radiator: Clarifying Confusion

AI Thread Summary
The discussion clarifies the calculation of the required area for a radiator, emphasizing that "Required Area" refers to the total area that effectively contacts the flowing air, including both the surface area on both sides and the cooling fins and tubes. A user expressed confusion over their calculated value of 0.6387m², which seemed larger than expected. Other participants noted that a finned radiator with this area may appear smaller than anticipated. The conversation highlights the importance of understanding the effective contact area in radiator design. Accurate calculations are crucial for effective radiator performance.

When calculating the required area for a radiator using the equation

Mass flow rate of air = Required Area x density of air x velocity of air

Does the Required Area mean the Surface area on both sides of the radiator OR does it mean the total surface area of the cooling fins and tubes etc. ?

The value that I acquired is 0.6387m^2 which seems to be substantially larger than I expected.
thanks in advance

Total area that comes in (effective) contact with the flowing air.

You'd be surprised how small the 0.64m² finned radiator will end up being.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
