Question

A 2.37 m wide by 1.17 m high metal plate must be insulated to prevent contact burn injuries.  If the heat transfer rate is 123 W and the temperature across the insulation must be reduced from 87.4°C to 42.7°C, what is the minimum thickness (in cm) of insulation required [round your final answer to two decimal places]?

{kins = 0.036 W/m∙K}
