For
heat transfer
1. how would one calculate the temperature of a probe at a
distance X from wall.
Thermal conductivity is known
Diameter is known
Extenernal ambient temperature is known
Surface heat transfer coefficient is known

Radiative heat transfer is negligible
2. How would one calculate rate at which energy is gained by
convection to the probe (using above information)
3. How to determine minimum length of probe to be considered
thermally infinite
