What is the osmotic pressure of the 3.5% solution in atm?
What is the osmotic pressure of the 3.5% solution in atm?
The osmotic pressure of the 3.5% solution is 30 atm.
What is the membrane permeability for water in L/m².h.atm?
What is the membrane permeability for water in L/m².h.atm?
The membrane permeability for water is 10 L/m².h.atm.
What is the estimation of membrane area required, assuming concentration polarization to be negligible?
What is the estimation of membrane area required, assuming concentration polarization to be negligible?
The estimation of membrane area required, assuming concentration polarization to be negligible, can be calculated using the formula: $A = \frac{Q(P_f - P_p)}{J}$, where A = membrane area (m²), Q = volumetric flow rate (m³/day), $P_f$ = feed pressure (atm), $P_p$ = permeate pressure (atm), and J = membrane permeability for water (L/m².h.atm).
If the mass transfer coefficient on the feed side is 4x10^-5 m/s, how do you recalculate the mass transfer area, taking concentration polarization into account?
