A large heated steel block ( = 7832 kg/m 3 , c p = 434 J/kgK, k
Question:
A large heated steel block (ρ = 7832 kg/m3, cp = 434 J/kg·K, k = 63.9 W/m·K, and α = 18.8 × 10–6 m2/s) is allowed to cool in a room at 25°C. The steel block has an initial temperature of 450°C and the convection heat transfer coefficient is 25 W/m2·K. Assuming that the steel block can be treated as a quarter-infinite medium, determine the temperature at the edge of the steel block after 10 min of cooling.
