Stainless steel type 304 [k = 16.3 W/m-K] from heat treatment was brought to a room @ 27C. It is in cube form and has an edge of side 20cm. Initially, the temp. of the steel from the heat treatment is 500C. The total effective heat transfer coefficient is 18 W/m2-K. How long will it take for the surface of the cube to be within 28 C of the room temp.?
