Question:
A 5 cm diameter copper sphere (ρ=8933 kg/m3;k=401 W/m⋅K;cv=385 J/kg⋅K) is initially at a uniform temperature of 250∘C when it is suddenly immersed in a fluid at 30∘C. The convection heat transfer coefficient between the sphere and the fluid is 28 W/m2⋅K. Estimate the time necessary for the temperature at the center of the sphere to reach 90∘C. ?
