Question:

A sphere 0.1 m diameter is rotating at 20 RPM in a large container of CO2 at atmospheric pressure. If the sphere is at 60?C and the CO2 at 20?C, estimate the rate of heat transfer.GIVENA rotating sphere in carbon dioxide at atmospheric pressureDiameter (D) = 0.1 mSpeed of rotation (w) = 20 rev/minSphere temperature (Ts) = 60?CCO2 temperature (T??) = 20?CASSUMPTIONSSteady state conditionsThe carbon dioxide is stillRadiation isnegligible
