- When 10 mL of water at 20oC is placed in an Ostwald viscometer, it takes 136.5 s for the liquid levelto drop from the first mark to the second. For 10 mL of hexane at 20oC in the same viscometer, thecorresponding time is 67.3 s. Find the viscosity of hexane at 20oC and 1 atm.(ηH2O=1.002 cP, dH2O= 0.998 g/cm3, dC6H14=0.659 g/cm3)A researcher wants to calculate the flux of palm oil (PO) in a simulated body fluid (SBF). To perform the experiment, he designed a 30 cm capillary tube. At the very beginning of the tube, he designed a partition with a separator as shown in the figure below. He filled the partition with a stock solution prepared by solving 10 g of PO in a liter of SBF and the capillary tube with pure SBF. Then he removed the separator. The viscosity of the BSF is 3.6x10-3 Pa.s and molecular weight of PO is 850.92.a. Calculate the flux of PO in kg mol/s.m2 at steady state. (Use Polson equation for diffusivity.) (Assume the temperature is maintained at 37oC during whole experiment.)b. Concentration of PO at the half of the tube.When the temperature is 20 ° C, water flows through an ostwald viscometer at 363 s, whose density and viscosity are given as 0.9982 g / cm3 and 1,000 cP, respectively. The flow time of OF2 from the same viscometer at -145.8 ° C was measured as 68 s. Since the density of OF2 at this temperature is 1.523 g / cm3, what is the value of its viscosity?
