Calculate the main term: $$ Nu = \left 0.6 + \frac0.387 (1.55 \times 10^9)^1/61.09 \right^2 $$ $$ Nu = \left 0.6 + \frac0.387 \times 17.781.09 \right^2 $$ $$ Nu = 0.6 + 6.31 ^2 = (6.91)^2 = 47.75 $$

The heat loss is approximately 1.19 kW . You can copy, paste, and edit this as needed

For an ideal gas, this property is inversely proportional to the absolute temperature:

Many natural convection problems require you to assume a film temperature, look up properties, calculate the Rayleigh number, find the Nusselt number, and then re-verify your initial assumptions. Solution Manual Content for Chapter 9: Natural Convection
