Question:
Air at 25°C flows over a 5-cm-diameter, 1.7-m-long smooth pipe with a velocity of 4 m/s. A refrigerant at -15°C flows inside the pipe and the surface temperature of the pipe is essentially the same as the refrigerant temperature inside. The drag force exerted on the pipe by the air is
(a) 0.4 N
(b) 1.1 N
(c) 8.5 N
(d) 13 N
(e) 18 N
(For air, use v = 1.382 × 10-5 m2/s, ρ = 1.269 kg/m3)
