Question
Suppose you stand with one foot on ceramic
(k=28 W/mK) flooring and one foot on a wool
carpet (k =0.024 W/mK), making contact
over an area of 62.5cm² with each foot. Both
the ceramic and the carpet are 2 cm thick
and are 5°C on their bottom sides. If the top
of the ceramic and carpet at 29°C, calculate
the following:
a) the rate of heat transfer that occur from
the foot kept on wool carpet in watts
b) the rate of heat transfer that occur from
the foot kept on ceramic in watts
