Temperature steps. A copper plate is of length / = 10 cm and w = 1 cm on a side and is mounted in a substrate such that its side and back surfaces are well insulated; the front surface is exposed to the air flow with the velocity of 1 m/s and at T = 20C. The temperature of plate is maintained at 20C from x = : 0 to X = 3 cm and 40C from x1 to x2 = 6 cm. The temperature from x2 to the L is maintained at 60C. Air properties: v = 20 x 10-6 m/s, Pr = 0.7, Kair= 0.03 W/mK. Copper properties: Kcopper = 400 W/mK. (a) Sketch q'(x) along the plate (0 < x Temperature steps.
