Air at \(25^{\circ} \mathrm{C}\) flows over a 10 -mm-diameter sphere with a velocity of \(15 \mathrm{~m} / \mathrm{s}\), while the surface of the sphere is maintained at \(75^{\circ} \mathrm{C}\).

(a) What is the drag force on the sphere?

(b) What is the rate of heat transfer from the sphere?

(c) Generate a plot of the rate of heat transfer from the sphere as a function of the air velocity for the range 1 to \(25 \mathrm{~m} / \mathrm{s}\).
