Answer:
Gas temperature is 3000 C
Convective coefficient, h = 75 W/m2. K
Initial temperature is 250 C
Sphere diameter is 75 mm
Gas temperature, = 300°C+273k = 573 K. Tuitial Temperature, Ti = 2256 ... = 25+ 373 Ti = 298k - For Aluminium-2024 Ait 5ook, Density; P = 2780 kg/m3 specific head, hs = 950J/kg-k Conductivity, k = 240 wlmik. a) Cheracteristic length; Le = diz hero.0125m =) Biot number, .
