Question: Transient Heat Transfer Problem

Hello,

I am trying to solve a transient heat transfer problem.

The problem is that I have an insulated pipe that is immersed in cold water.  At time 0, the fluid filling the pipe is at a constant temperature.  The insulation at one end of the pipe is different to the rest of the insulation.  I need to find out the time that it would take any fluid to reach a certain temperature, called the cool down time.

A graphic representation of the problem with the data that should be required to solve the problem is as shown in the figure

Any assistance would be greatly appreciated.

Best regards
