- A solution to a problem regarding temperature entering a length of ducting at which the exit temperature needs to be calculated

Hello,

I am looking for assistance regarding temperature losses along a length of pipe with hot air entering one. I need to know the temperature leaving the other end of the pipe.

I have been able to calculate the W/m-K (in theory but stopped a i knew the answer wasnt what i needed) losses but was hoping to be able to calculate the temperature loss.

Info:

Pipe OD = 105mm

Pipe ID = 100

Flow rate of air = 800L/min

Air temp entering pipe = 200°C

Ambient temp = 30°C

Flow type - Laminar

Material = Not yet decided but any ABS plastic can be assumed (open on values regarding material for now)

i have been reading 2009 ASHARE handbook but with no achieved results. Any help would be greatly received.
