Hot combustion gases approximated as air at \(1 \mathrm{~atm}\) and \(350^{\circ} \mathrm{C}\) flow in a \(16-\mathrm{cm}\)-diameter steel pipe at a velocity of \(3.5 \mathrm{~m} / \mathrm{s}\). The roughness of the pipe is \(0.045 \mathrm{~mm}\). The required power input to overcome the pressure drop for a pipe length of \(60 \mathrm{~m}\) is

(a) \(0.55 \mathrm{~W}\)

(b) \(1.33 \mathrm{~W}\)

(c) \(2.85 \mathrm{~W}\)

(d) \(4.82 \mathrm{~W}\)

(e) \(6.35 \mathrm{~W}\)
