A large 2.54-cm.-thick copper plate is placed between two air streams. The heat transfer coefficient on the one side is 28 W/(m2 K) and on the other side is 57 W/(m2 K). If the temperature of both streams is suddenly changed from 38?C to 93?C, determine how long it will take for the copper plate to reach a temperature of 82?C.GIVENA large copper plate between two air streams whose temperatures suddenly changePlate thickness (2L) = 2.54 cm = 0.0254 mThe heat transfer coefficients are hcl = 28 W/(m2 K)hc2 = 57 W/(m2 K)Air temperature changes from 38?C to 93?CASSUMPTIONSThe initial temperature of the plate is 38?CThe plate can be treated as an infiniteslab
