To defrost ice accumulated on the outer surface of an automobile windshield, warm air is blown over the inner surface of the windshield. consider an automobile windshield with thickness of 5 mm and thermal conductivity of 1.4 w/m·k. the outside ambient temperature is 210°c and the convection heat transfer coefficient is 200 w/m2·k, while the ambient temperature inside the automobile is 25°c. determine the value of the convection heat transfer coefficient for the warm air blowing over the inner surface of the windshield necessary to cause the accumulated ice to begin melting.
