SUMMARY

This discussion focuses on calculating heat flux (Q) without knowing thermal conductivity (K). The equation Q=K(Th-Tc)/(x) is central to the conversation, emphasizing the relationship between heat flux, temperature difference, and material thickness. Participants suggest exploring alternative experimental methods to measure heat or power when material properties are unknown. The need for innovative approaches in scenarios where density or melting temperature cannot be tested is highlighted.

PREREQUISITES
  • Understanding of heat transfer principles
  • Familiarity with the equation Q=K(Th-Tc)/(x)
  • Basic knowledge of thermal properties of materials

How to calculate K or Q without one or the other?
For example, if the material is unknown (but cannot test density, or melting temperature)
how would you test heat flux?

Q=K(Th-Tc)/(x)

In the homework section the rules require you to make an attempt to answer.

Perhaps think about other experiments that involve measuring heat or power.
