4 mm thick glass windows of an automobile have a surface area of A = 2.6m ^ 2 The outside temperature is T x00 = 32 deg * C while the passenger compartment is maintained at T ei =22^ C The convection heat transfer coefficient on the exterior window surface is h_{a} = 90W / (m ^ 2) K. Determine the heat gains through the windows when the interior convection heat transfer coefficient is h_{i} = 15W / (m ^ 2) * K By controlling the airflow in the passenger compartment the interior heat transfer coefficient can be reduced to h_{i} = 5W / (m ^ 2) K without sacrificing passenger comfort. Determine the heat gain through the window for the reduced inside heat transfer coefficient.
