Length= 0.5m

k (heat coefficient for stainless steel)= 25

Internal Diameter= 73.2mm

Outside Diameter= 76.2mm

Outside Temperature= 206°C

Inside Temperature= ?

I managed to get the inside temperature at the exhaust exit which gave me...

Inside Temperature= 171°C

Outside Temperature= 90°C

With that I was able to use the formula:

Heat Transfer = ((2 * pi * k * L)/(Ln(Outside Dia/Inside Dia)) * (Inside Temp - Outside Temp)

This gave me a heat transfer figure of 159,043.5W

Whether any of that helps me figure out the temperature further up the exhaust pipe I have no idea. Especially considering I don't know the internal temperature of the gas at that section of piping. Anyone got any ideas?
