In an annealing process-a process wherein materials such as glass and metal are heated to high temperatures and then cooled slowly to toughen them–the following equation may be used to determine the temperature of a thin piece of material after some time t. 2h exp pcL T -T environment T -T initial environment where T = temperature (°C) h= heat transfer coefficient p= density (kg/m³) c= specific heat (J/kg - K) L= plate thickness (m) t= time (s) Those of you who will pursue aerospace, chemical, mechanical, or materials engineering will learn about the underlying concepts that lead to the solution in your heat-transfer class. What is the appropriate unit for h if the preceding equation is to be homogeneous in units? Show all steps of your work.
