Question:
A monolithic membrane element, of the type shown in figure d, contains 19 flow channels that are 0.5 cm in inside diameter by 0.85 m long. If nine of these elements are placed into a cylindrical module of the type shown in figure, determine reasonable values for:(a) Module volume in m3.(b) Packing density in m2/m3. Compare your value with values for other membrane modules given in Table14.4.
