Suppose a small stoneware kiln with surface area 5m 2 sits in a room that is kept
Question:
Suppose a small stoneware kiln with surface area 5m2 sits in a room that is kept at 25 ◦C by ventilation. The 15 cm thick walls of the kiln are made of special ceramic insulation, which has k = 0.03W/mK. The kiln is kept at 1300 ◦C for many hours to fire stoneware. The room ventilating system can supply 1.5 kW of cooling. Is this adequate?
