Engineering Riddle – No. 6 (Heat Transfer) “I Scale”
I scale in a wind-storm, I scale in a flood
I scale in tornadoes, I scale in the mud
I scale in an oven, the air blistering heat
I scale in a wind-chill, rain, snow or sleet
I scale when it’s calm, or in a twirling spin
I scale with exposure, when gas goes ‘cross the skin
I scale when a flying, I scale in the sky
I scale when a swimming, and even when it’s dry
I scale on the surface, I scale from the wall
I scale whether hot or cold, or whether big or small
I scale several factors, that govern flow of heat
I scale how much energy, will cross the gaseous street
I scale on the surface, from each end of the field
I scale whether hot or cold, my scaling will not yield
I scale in the vapor, when temperatures are different
I scale, yes, that’s all I do; I’m just a coefficient
What am I?
Prandl Number
The answer is probably more scientific, but…a thermometer?
Very nice guess. The answer is not a thermometer, it is a particular ‘coefficient’ used in an equation in the science of heat transfer.
