At 250C, the interfacial tension between water and n – octyl alcohol is 8.50 dyne/cm. if the surface tension of n-octyl is 27.53 dyne/cm and that of the water is 72.75 dyne/cm, predict whether water spreads on the alcohol by calculating a) Work of cohesion of n-octyl b) Work of adhesion and c) the spreading coefficient of water on the alcohol. Will alcohol spread on water?

Intro to Transport Processes TRUE or FALSE. Please provide a quick explanation thanks! 1. Each molecule of a system has a certain quantity of mass, thermal energy, or momentum associated with it. 2. Momentum transport in a fluid depends bulk movement of molecules and not on individual molecule of the system.  3. At same mass, the momentum of a molecule is greater than the other molecules if it has less velocity?

Hello could you please solve it by showing each step, make sure its easy to understand what to do on each step thanks

You are developing a porous membrane for use in a dialysis system. The membrane must be able to retain both protein and glucose on the inlet side and allow other, smaller molecules to flow through. You have found that the membrane is 0.25 mm thick and contains long, rectangular pores with a width of 0.1 microns. 57% of the 50 cm^2 membrane surface area is covered with pores. A test fluid (viscosity = 1.5 cP, density = 1015 kg/m^3) is passed through the membrane. You can assume that the test fluid has a composition similar to that of blood plasma. An initial test is run at physiological conditions, and you observe that the flow rate of fluid through the membrane is 500 cm^3/min. Given this data, what must the hydrodynamic pressure drop across the membrane in your test system be in pascals?
