Question:
A hollow-fiber module has 4,000 ft2 of membrane surface area based on the inside diameter of the fibers, which are 42 ?m i.d. x 85 ?m 0.d. x 1.2 m long each. Determine:(a) The number of hollow fibers in the module.(b) The diameter of the module, assuming the fibers are on a square spacing of 120 pm center-to-center.(c) The membrane surface area per unit volume of module (packing density) m2/m3. Compare your result with that in Table 14.4.
