    Abstract The objective of this lab was to determine the convective heat transfer coefficient of a heated sphere in an quiescent environment. In the experiment a hot brass sphere was put into water and cooled. The temperature of the sphere was recorded over a time of 600 seconds to see how it cooled and given temperature was recorded every 20 seconds. Results were then calculated at both of the time values 300 and 600 seconds. For the experimental results at time 300 seconds‚ the Rayleigh number
