Question:
A die cast component has a mass of 1.2 kg and density 7150 kg/m322 with surface area of 0.075 m. The thermal conductivity of the material is 95 W/mK and the specific heat is 385 J/kg K. It comes out of the machine at 345°C and is exposed to air at 20°C with a convective heat transfer coefficient of 56.8 W/mK. Determine
(i) The temperature of the part after 5 minutes
(ii) The time required to reach 50°C
(iii) The time constant
(iv) The value of convective heat transfer coefficient up to which the lumped parameter model can be used
(v) The volume/area ratio up to which the lumped parameter model can be used.
