Two metal plates with the same dimension are soldered together face to face. The face of plate 1 that is not touching plate two is keep at T1 = 106 0C. Similarly, plate 2 “open face” is keep at T2 = 0 0C. Assume the thickness of each plate is 3.0 mm and their areas are 82 cm2. For plate 1, K1 = 48.1 W/m-k and for plate 2, k2 = 68.2 W/m-k. Find the heat flow through the plates.
