(a) Verify that the equation is dimensionally correct.

(b) Estimate the rate of heat transfer, Q, for the flow around a sphere of diameter 1 min. The fluid is an oil at T8 = 50Â°C moving at a velocity 1.0 cm/sec with respect to the sphere, the surface of which is at a temperature of 100Â°C. The oil has the following properties: p = 0.9 g/cm3, Cp = 0.45 cal/g Â· K, k = 3.0 x 10-4 cal/s Â· cm Â· K and Âµ = 150 cp.
