Air at 20°C and 1 atm flows over a spherical object at 1 m/s. The sphere has a diameter of 10mm and its initial temperature is 134°C. If the density, specific heat, and conductivity of the sphere are 7832 kg/m”, 549 J/kg.K, and 49.2 W/m.K, respectively, calculate the temperature at the center of the sphere after 100 seconds.
