A large brass plate of thickness 5 cm is initially at a uniform temperature of 15 C, and is passed through an oven held at 800 C for some period of time. You may assume that brass has a specific heat capacity of c_P = 380 J kg^-1 K^-1, density = 8530 kg m^-3, and a heat conductivity k = 110 W m^-1 K^-1. You may also assume a heat transfer coefficient h = 120 W m^-2 K^-1.

Calculate the Biot number for this scenario
