1. Homework Statement
I have to find the energy removed through conduction from a copper pipe.
Pipe Inner Diameter (Din): 8mm
Pipe Wall Thickness (Dout): 1mm
Thermal Conductivity (k): 401W/m.K
Temp inside pipe -150C, Outside 30C
Length (L)=1m


2. Homework Equations
The Equation I used was as follows:
(Tout - Tin)/R=Q/s
Where R= ln(Dout/Din)/2.PI.k.L


3. The Attempt at a Solution
I ended up getting approximately 2050kW
Which too me seemed a bit high... Would just like someone else to validate I did everything correct.

Thanks
