For a metal plate (k = 50 W / m°C and a = 0.000030 m^2 / s) that is at a uniform initial temperature of 90 °C, and which is exposed to a current of air at 20°C with a heat transfer coefficient of 210 W / m2°C on the surface, determine the temperature at the surface and at a depth of 10 cm after 3 minutes of exposure. Assume a semi-infinite surface, one- dimensional conduction, and constant thermophysical properties
