Air at \(1 \mathrm{~atm}\) and \(20^{\circ} \mathrm{C}\) flows in a 3-cm-diameter tube. The maximum velocity of air to keep the flow laminar is

(a) \(0.87 \mathrm{~m} / \mathrm{s}\)

(b) \(0.95 \mathrm{~m} / \mathrm{s}\)

(c) \(1.16 \mathrm{~m} / \mathrm{s}\)

(d) \(1.32 \mathrm{~m} / \mathrm{s}\)

(e) \(1.44 \mathrm{~m} / \mathrm{s}\)
