A circular pipe of \( 25-\mathrm{mm} \) outside diameter is placed in an airstream at \( 25^{\circ} \mathrm{C} \) and 1-atm pressure. The air moves in cross flow over the pipe at \( 15 \mathrm{~m} / \mathrm{s} \), while the outer surface of the pipe is maintained at \( 100^{\circ} \mathrm{C} \). What is the value of the dimensionless heat transfer coefficient gf the pipe?
