Rise in room temperature over a one hour period

AI Thread Summary
The discussion centers on calculating the temperature rise in a room with no cooling, measuring 5m x 4m x 2.5m, and experiencing a heat dissipation of 65kW. The ambient temperature is initially set at 20 degrees Celsius. It is suggested that, if perfectly insulated, the room could see a temperature increase of around 3600 degrees Celsius in one hour, highlighting the unrealistic nature of this figure. The actual temperature rise would occur rapidly, approximately 1 degree Celsius per second, until heat outflow matches the heat input. The conversation emphasizes the importance of considering heat dissipation and insulation in temperature rise calculations.

I have a room with no cooling.

Room info : w = 5m l = 4m h= 2.5m
Heat dissipation from equipment in room= 65kw
Ambient temp = 20 degrees celcius

I need to know the temperature rise over a one hour period

Please help

Thanks

If the room is perfectly insulated and held at a constant pressure (not perfectly sealed), I get a back of the envelope answer that it will rise in temperature by about 3600C in an hour. Obviously, this isn't correct, but this demonstrates that the room will rapidly rise in temperature (~1 degree C per second) until the heatflow out through the walls and whatever venting system exists is equal to the heatflow in.
 
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...
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...
