Multiscale Modeling Of A Gas Separation Device

However, when the membrane was changed to from 20 MWCO to 50 MWCO, the Na+ Cl- molecules were able to diffuse through the membrane, the equilibrium would be reached and no osmotic pressure was generated. If the concentration of Na+ Cl- of both size are equal, the osmotic pressure would be zero.

Procedure: Have you made any changes to the procedure? Please explain. If you made no changes, state so. (1 point)

2. Read and record the temperature of the gas using the thermometer attached to the container.

The programmed algorithm is shown in Figure 6.The program was developed using LabVIEW System design software. The entire experimental set-up is shown in Figure 7.

All CAD models were constructed via Siemens NX 9.0 and imported into advanced simulation mode to conduct FEA.

Once inverted, built-up gas was released by turning the stopcock to its opened and closed positions. This was repeated for about four times in one minute intervals. Then the layers were allowed to settle until a separation between liquids could be observed. Due to the low density of the product, the top layer was to be extracted. The bottom layer was carefully and slowly extracted out of the separatory funnel.

5.Position gas collecting hose so it runs from reaction vessel through gas collecting box to opening of the graduated cylinder. The idea is that any gas coming through the tube will rise in the graduated cylinder and displace the water in it.

1). Design the circuit for the given specifications. 2). Write the program code. 3).

The purpose of this experiment is to investigate some physical and chemical properties of gases and to use these properties to identify these gases when they are encountered.

Small pockets of the specific liquid, that contains trapped gas, that is then released to the

Assuming no viscous forces present an inviscid model has been used for the calculations. Also from the equation of the Reynolds number Re=ρvl/μ due to Re being really big rearranging and assuming v and l to be constant the viscous force μ =ρvl/Re becomes negligible.

suspects that the gas comes from the ring of solid particles (5). If he is

The gas then travels into the collecting tube and condenses through the tube into the collecting test tube. This technique separates pure substances into fractions. In this case, acetone was

Low temp for drying the sample , then the wall is heated up to 1400 K for short period to ash the sample, then up to 2550 K for few seconds to produce gas phase atoms.
