In summary, the conversation discusses a question about determining the temperature of air 100mm away from a 300mm diameter steel pipe at a temperature of 200deg C. The participants mention the need to specify the material and composition of the object being measured, as well as providing helpful links for guidance on heat transfer. The conversation also includes a follow-up question about the temperature of air 100mm from a 300mm X 600mm steel plate with a surface temperature of 200deg C.

Hi Guys,

Is there an easy way to determine this?

Say I have a 300mm Dia Pipe that @ 200deg C, ambient temp 30gec C.

What would be the Temp 100mm away from the surface.

Thanks in advance

You need to specify what the pipe is made of, if it is painted/coated etc. Also you need to specify the composition of what you are measuring 100 mm away (another pipe? your face? air?) in order to determine what the temperature of that object would be. Otherwise you can only calculate the heat flux of the pipe.

The pipe is made of unpainted steel and I would like to know the temp of air.

So if I had a 300mm X 600mm Steel Plate who's surface temp is 200deg C

What would be the temp of Air 100mm From the surface?

What the equation to work this out?

Thanks

1. How do you calculate heat loss?

To calculate heat loss, you need to know the temperature difference between the inside and outside of a space, the surface area of the space, and the insulation value of the materials used. The formula for calculating heat loss is: Heat Loss = (Temperature Difference * Surface Area) / Insulation Value.

2. What is the significance of distance in calculating heat loss?

The distance between the inside and outside of a space is an important factor in calculating heat loss because it affects the temperature difference. The greater the distance, the greater the temperature difference, and therefore, the greater the heat loss.

3. How does insulation affect heat loss?

Insulation plays a crucial role in reducing heat loss. The higher the insulation value, the lower the heat loss will be. Insulation acts as a barrier to prevent heat from escaping through walls, floors, and ceilings.

4. Can heat loss be prevented?

While it is impossible to completely prevent heat loss, it can be significantly reduced through proper insulation, sealing air leaks, and using energy-efficient windows and doors. These measures can also help save on energy costs.

5. Are there any other factors that can impact heat loss?

Yes, other factors that can impact heat loss include outside temperature, wind speed, and the type of heating system being used. Higher outside temperatures, strong winds, and inefficient heating systems can all lead to increased heat loss.
