Problem statement: In a laboratory experiment, researchers designed a setup for measuring water flux in an osmotically-driven membrane cell. Water flux (Jw) in the member is a function of the high concentration draw solution osmotic pressure (D), the low concentration feed solution osmotic pressure (F), intrinsic membrane permeability (A w), and the filtration constants k and K. The equation for water flux (Jw) calculation is: = [ () 1 + (() ) ] For this experiment: k constant is 0.175 m/h, K constant is 29 h/m, B = 0.0004 m/h, and A w constant is 0.00158 m3 /m2 .h.bar. Calculate water flux in the filtration experiment for: 1. 24 D34 at F = 1 bar, using D step of 2 bar. Plot D vs Jw of the experiment 2. 31 D41 at F = 5 bar, using D step of 2 bar. Plot D vs Jw of the experiment Note: Jw units is L/m2.h F and F units is bar All units are in SI standard
