Repeat Example 9.3, but with a feed pressure of 5.0 MPa. Compare your results to those obtained at a feed pressure of \(1.0 \mathrm{MPa}\).

Data From Example 9.3:-

Consider the air separation problem of Example 9.2. In this case, the separation will be performed in a hollow-fiber module using the same PEMA membrane and operating in a cross-flow mode. For the same operating pressures considered in Example 9.2, calculate the cut, composited permeate concentration, and membrane area required to produce a retentate oxygen concentration of 7%. Compare these results to those obtained for perfect mixing in Example 9.2.
