Answer the following statement true (T) or false (F)
Air flows in a 4-cm-diameter wet pipe at 20°C and 1 atm with an average velocity of 4 m/s in order to dry the surface. The Nusselt number in this case can be determined from Nu = 0.023 Re0.8 Pr0.4 where Re = 10,550 and Pr ?= 0.731. Also, the diffusion coefficient of water vapor in air is 2.42 × 10?5 m2/s. Using the analogy between heat and mass transfer, the mass transfer coefficient inside the pipe for fully developed flow becomes
(a) 0.0918 m/s (b) 0.0408 m/s (c) 0.0366 m/s (d) 0.0203 m/s (e) 0.0022 m/s
