Question

8. A depth filter has been converted to an idealized model and can be described mathematically. The target efficiency of one individual fiber is 30% Each row of fibers has collection fibers spaced 6 fiber diameters apart as measured center to center. (Hint: calculate the percentage of open and closed area). In other words, each fiber has a diameter de and the fibers are spaced 6 dp apart, center to center. Now, the overall filter can be described as 30 such sets of these individual screens in series, each perpendicular to the flow. Determine the overall collection efficiency

Explanation / Answer

Overall efficiency = 1-?(1-each fibre efficiency)

Each fibre efficiency=30%=.3

Number of fibre = 30

=> Overall efficiency= 1-(1-.3)^30=99.99%
