AI Thread Summary
To produce 100,000 BTU/s in a typical house, approximately 10 pounds of coal per hour is needed, based on an energy density of 10,340 BTU/lb. In colder climates, such as Maine, a heating rate of 100,000 BTU/hr is common for medium to large homes. The specific heat of coal can vary significantly, with high-quality anthracite offering around 17,000 BTU/lb, while lower-grade Texas brown coal may only provide 2,500 BTU/lb. It's crucial to determine the specific heat of the coal being used to ensure accurate calculations. Understanding these factors is essential for effective heating solutions.

how much coal is required to produce 100000 BTU/s in a typical house?

I have been looking and looking with no leads on it

need help please

I am a plumbing, heating, and cooling contractor in Maine. 100,000 btu/hr is normal for a house up here with a -10 design temp. We use 12,000 btu's per lb for bulk or bag coal. It has always worked for us.
 
The specific heat of coal varies all over the map. Really good Pennsylvania anthracite (virtually unavailable now) was as high as 17,000 btu/lb, while some Texas brown coal is as low as 2500 btu/lb. Be sure to get the correct specific heat for the coal you plan to use.

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 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
