Oxygen enters a 6-in.-diameter duct with \(T_{1},=600^{\circ} \mathrm{R}, p_{1}=50 \mathrm{psia}\), and \(V_{1}=600 \mathrm{ft} /\) sec. The friction factor is \(f=0.02\).

(a) What is the maximum length of duct permitted that will not change any of the conditions at the inlet?

(b) Determine \(T_{2}, p_{2}\), and \(V_{2}\) for the maximum duct length found in part (a).
