None of that matters. If a surface is wet, evaporative cooling can drop the temperature. Once the water evaporates the surface will warm to the ambient temperature. Since you are talking about a liquid in pipes (and the outside of the pipes is dry), the wind does not matter. Higher wind speeds actually tend to warm things up a bit by mixing down warmer air if an inversion had developed. Use whatever temperatures you like but the physics are clear.

Since I am not sure how water may or may not be affected in the equation I tend to use a lower temperature potential as is practical.
