determine the temperatures at the center of the resistance wire
and the interface of the wire and the ceramic layer under steady conditions
the bottom surface of the plate is monitored by an infrared (IR) thermometer.
Obtain an expression for the variation of temperature in the metal plate. The
IR thermometer measures the bottom surface of the plate to be 60°C. Determine
the minimum value of the convection heat transfer coefficient necessary
to keep the top surface below 47°C to avoid instantaneous thermal burn upon
accidental contact of hot metal surface with skin tissue
