Hi! I have a problem that I need to solve. I was really hoping someone could help me get started. It should be simple...(adsbygoogle = window.adsbygoogle || []).push({});

I have a pipe made out of copper with an inner diameter of 50mm and a thickness of 5mm (i.e. outer diameter is 55mm). Around this pipe is an isolating layer with a thermal conductivity of 0.04W/(mK) followed by a plastic layer with a thermal conductivity of 0.15W/(mK). The total diameter of the pipe is 160mm.

Now we want to send water with an initial temperature of 80C (about 353K) through the pipe. The water travels at a speed of 0.5m/s and the temperature of the surrounding is 7C (about 280K).

I need to approximate the temperature of the water after 1km.

I of course do not expect anyone to solve this for me; I just need help getting started.

Thanks in advance!
