What Are the Requirements for Part B?

  • Thread starter Logistics
  • Start date
In summary, the conversation is about heat transfer through conduction and the formula for calculating heat current using the variables Q/t, dT, K, A, and x. The question in Part B is asking for the calculation of heat current using these variables.

This question is with regards to the heat transfer through conduction.

Heat Current means Total heat energy liberated per second.

Go for the formula:

Q/t=dTKA/x

Where Q/t=heat current

dT=difference in temeperatures on both side of the walls(140 in the question)

K=Thermal conductivity=0.04 (given)

A=Area of the cross section

x=length of the cross section
