Key formula: equation for, but this question is really about knowing what information is actually needed
Calc: Well, this T ambient is 70 degrees.
Calc: It's entering at 130 degrees, and by the time it leaves the room, it's all the way down to 110 degrees.
Result: But that's what we're going to use as our input is an average surface temperature, the outside of the pipe that's equal to the bulk temperature.
