A75 um thick polysulphone microporous membrane has an average porosity of e 0.35. pure water flux through the membrane is 35 m'/m h at a pressure drop of 2 bar at 25°c. the average pore size is estimated to be 0.8 um. calculate the tortuosity factor of the pores, the resistance to flow offered by the membrane and its water permeability. the viscosity of water at 25°c is 0.9 cp

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

12 is it do you think so
