Density and viscosity oleic acid at 20 degree celcius and 1 atm

Calculate the viscosity of oxygen at 350 K and 1 atm pressure using equation 7.12 on page 90 of the text (also found in the PowerPoint slides).and compare with the value in Appendix I.

An acetal polymer block is fixed to the rigid plates at its top and bottom surfaces. If the top plate displaces 5 mm horizontally when it is subjected to a horizontal force P = 2 kN, determine the shear modulus of the polymer. The width of the block is 100 mm. Assume that the polymer is linearly elastic and use small angle %3D analysis.

5. The following table shows data from a flow study of a PS melt at 210°C in a capillary rheometer. a. Make a plot of log shear stress versus log shear rate. b. Calculate the value of the viscosity at 1 and 135 s', respectively. Shear Stress ,(10° dyn/cm') Shear Rate, 3.5 1.0 12.0 5.0 20.0 12.2 33.0 25.0 40.0 52.5 60.0 135.0 69.8 400.0
