At 25 °C in a lab membrane with area A = 2 *10-3 m2 we feed a solution of 10 kg NaCl per m3 solution so well mixed that essentially it has the same strength leaving.
The permeate is measured as 0.39 kg NaCl per m3 solution at a rate of 1.92 * 10-8 m 3.s-1 when applying a constant pressure difference of 54.42 atm.
Calculate:
1. the permeance constants for the solvent
2. the permeance constants for salt (these type of constants are previously given, but this question shows
how they may be calculated experimentally)
3. the rejection coefficient.
