Calculate the heat transfer coefficient for a rate of free convection heat loss from a 30 cm diameter sphere maintained at 100°C and exposed to atmospheric air at 20°C.
The following properties are given:

ρ = 1.06 k g / m^{3}, C_{p} = 1008 J / k g K

k = 0.028.5 W / m K; μ = 20.03 \times 10^{- 6} k g / m . s

v = 18.97 \times 10^{- 6} m^{2} / s e c; β = \frac{1}{333} K^{- 1}

Use the following correlation if required:

N u = 0.53 (G r . P r)^{1 / 4}
