The windshield of an automobile is heated on the inside by a flow of warm air. Cold air at -15 F flows over the exterior of the windshield. The heat transfer coefficient on the inside is 16 Btu/hft^2 F, and the heat transfer coefficient on the outside is 49 Btu/hft^2 F . The glass of the windshield has a thickness of 0.25 in. What temperature should the inside air be so that the exterior surface temperature of the windshield is 3 F?
