Week 7

In week 7, the group created a third heat pipe. With the first two, the water leaked out when testing. So, the group decided this time to solder one end of the heat pipe cap on and then attach a screw cap to the other side. Wrapped on the screw cap as well,  is Teflon tape that should hold the caps on tight and be able to withstand high heat. With this, hopefully it would prevent the leaking. Below show the materials used in this heat pipe.
Materials:
Copper Mesh
Copper pipe
10mL water
Copper caps
Teflon Tape

 The group created the heat pipe similar to the steps before.

Also in week 7, the group tested the heat pipe.

Testing went very well. The heat pipe didn't leak water as the first two experiments did. Below is the data gathered and a graph of the heat pipe temperature with time. The temperature seems to increase linearly with time.
