90% of people marry there 7th grade love. since u have read this, u will be told good news tonight. if u don't pass this on eight comments your worst week starts now this isn't fake. apparently if u copy and paste this on ten comments in the next ten minutes you will have the best day of your life tomorrow. you will either get kissed or asked out in the next 53 minutes someone will say i love you.!

A 75 um thick polysulphone microporous membrane has an average porosity of E 0.35. Pure water flux through the membrane is 35 m'
Paul [167]

Explanation:

The given data is as follows.

           Water flux, J_{w} = 25 m^{3}/m^{2}h

                                       = \frac{25}{3600} m^{3}/m^{2}h

So, let velocity (u) = \frac{25}{3600} m/s = 6.9 \times 10^{-3}

             \rho = 998 kg/m^{3}

             Pore size, d = 0.8 \times 10^{-6} m

             \mu = 0.9 cP = 9 \times 10^{-4} Pa.s

Hence, calculate the reynold number as follows.

                 R_{e} = \frac{\rho \times u \times d}{\mu}            

                        = \frac{998 kg/m^{3} \times 6.9 \times 10^{-3} \times 0.8 \times 10^{-6} m}{9 \times 10^{-4} Pa.s}    

                        = 612.1 \times 10^{-5}

                        = 0.006

This means that the flow is laminar.

Now, we use Hagen-Poiseuille equation as follows.

             J_{w} = \frac{\varepsilon \times d^{2}}{32 \times \mu \times \tau} \times \frac{\Delta P}{L_{m}}

where,     \varepsilon = membrane porosity = 0.35

                              d = 0.8 \times 10^{-6} m

                       \Delta P = 2 \times 10^{5} Pa

                      \mu = 9 \times 10^{-4}

                      \tau = tortuosity

                      L_{m} = membrane thickness = 75 \times 10^{-6} m

                    \frac{25}{3600} = \frac{0.35 \times (0.8 \times 10^{-6})}{32 \times (9 \times 10^{-4}) \times \tau}

                            \tau = 3.73

Hence, the tortuosity factor of the pores is 3.73.

As flow resistance = R_{m}

               J_{w} = \frac{\Delta P}{r \times R_{m}}

               R_{m} = 3.2 \times 10^{10} m^{-1}

Water permeability is represented by L_{p}.

                    J_{w} = L_{p} \times \Delta P  

             6.9 \times 10^{-3} = L_{p} \times 2 \times 10^{5} Pa  

              L_{p} = 3.45 \times 10^{-8} m^{3}/m^{2}s Pa

Therefore, the resistance to flow is 3.2 \times 10^{10} m^{-1} and its water permeability is 3.45 \times 10^{-8} m^{3}/m^{2}s Pa.

Which participates in chemical reactions?<br><br> electrons<br> protons<br> neutrons<br> gamma rays
KIM [24]
I think the correct answer is electrons. All chemical reactions are dependent on the transfer of electrons. Other subatomic particles are located in the innermost portion of an atom and are bonded strongly with each other.
