b) A rectangular shape of Lithium Iron Phosphate as shown in Figure Q1 battery generating a heat that results in a constant temperature of 45C. At the inside surface of the battery cover that is made from polypropylene plastic. The plastic thickness is 2 mm with a thermal conductivity of 0.44 W/m.K. The cover is then wrapped with a 5 mm graphite sheet (thermal conductivity of 600 W/m.K) and act as a cold plate to promote heat to transfer. The other side of the cold plate is exposed to both ambient air at 25C with a convection heat transfer coefficient of 2 W/mK and radiation heat transfer. If the heat only transfers in one direction, determine the radiation heat transfer per unit area.
