Two inches of urethane foam will reduce heat loss close to 1000% when applied to a 2-inch diameter uninsulated steel pipe. Assume the pipe wall thickness is 0.25-inches, the pipe interior convective heat loss (hi) is 500 BTU/hr-ft2-oF, and the pipe outside convective heat loss ho 20 BTU/hr-ft2-oF, k steel is 25 BTU/hr-ft-oF, and k insulaton is 0.023 BTU/hr-ft-oF. (hint - calculate heat loss with and without insulation.
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.?
