A 3-mm thick panel 1 m x 1 m of aluminum alloy k 177 wm k

A 3-mm thick panel (1 m x 1 m) of aluminum alloy (k = 177 W/m. K, Cp = 875 J/kg. K, and p(rho)= 2770 kg/m3) is heated in a large oven with air at T = 175oC and a convective heat transfer coefficient of h = 40 W/m2.K. The thermal conductivity of air at 175oC is 37.3 x 10^-3W/m. K. Calculate: (a) Biot number to assess the validity of the lumped parameter analysis. (b) Determine the time required to reach the temperature of panel 150oC if the panel is placed in the oven at an initial temperature of 25^oC.
