A hairstylist has a curling iron and a hairdryer plugged in and
operating at the same time. The devices are on a table such
that the hairdryer is blowing hot air over the exposed cylinder of
the curling iron. What is the convection heat transfer
coefficient that the hairdryer is making? Curling iron dimensions:
polished iron, diameter = 3-cm, length = 30-cm, surface
temperature = 65 deg C. Hairdryer dimensions: diameter -5-cm,
velocity = 2 m/s, air temperature at nozzle exit = 35 deg C.
