The underlying sketch shows a typical connection between a mullion and rail in a stick-built curtain wall. Using a leader line and label, identify: (i) shear block and (ii) bottom cover of rail. Explain how the bottom cover is attached to the top part of the rail.
What will be an ideal response?
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
