Note: This question paper contains two parts A and B. Part A is compulsory which carries 25 marks. Answer all questions in Part A. Part B consists of 5 Units. Answer any one full question from each unit. Each question carries 10 marks and may have a, b, c as sub questions.
Part A
Define Permeability.
Answer
Permeability is the measure of the ability of a porous material or membrane to allow the passage of fluids or gases through it under a given pressure gradient. It is typically defined as the flux per unit driving force.
Name any two types of synthetic membranes.
Answer
Two common types of synthetic membranes are polymeric membranes (e.g., polysulfone, cellulose acetate) and ceramic membranes (e.g., alumina, zirconia).
