18.13 In the curing of rubber tires, the “vulcanization" process requires that a tire carcass, originally at 295 K, be heated so that its central layer reaches a minimum temperature of 410 K. This heating is accomplished by introducing steam at 435 K to both sides. Determine the time required, after introducing steam, for a 3 cm-thick tire carcass to reach the specified central temperature condition. Properties of rubber that may be used are the following: k=0.151 W/m · K, cp=200 J/kg · K, p=1201 kg/m³, a=6.19 × 10¬8 m²/s. ||
