1. A heated copper wire 1 mm in diameter is in a pool of water at 1 atm. What is the maximum heat flux (q/A)max?
The temperature difference is related to the heat flux (q/A) by the following equation:

cpΔT/Prλ = 0.013[(q/A)μλ(√σ/g(ρL-ρv))]^1/3

What temperature difference ΔT = (Twire-Twater) and the properties are for the liquidat the saturation temperature. What temperature difference (which we'll call ΔTmax) is associated the maximum heat flux (q/A)max? What is the corresponding heat transfer coefficient for this maximum heat flux situation?

If the water were in the film boiling regime, what is the heat transfer coefficient corresponding to ΔTmax? Estimate the temperature difference ΔT needed to achieve the maximum heat flux in the film boiling regime.

What is the required wire temperature?

How does this compare with the melting point of copper?
