For a steel ball bearing (diameter 2 mm and density 7.8 g/cm3) dropped in glycerin (density 1.3 g/cm3 and viscosity 12 Ns/m2 at STP), the dominant drag force is the linear drag given by (2.82) of Problem 2.2. (a) Find the characteristic time t and the terminal speed vt. [In finding the latter, you sh

Consider an object that is coasting horizontally (positive x direction) subject to a drag force f = by cv2. Write down Newton's second law for this object and solve for v by separating variables. Sketch the behavior of v as a function of t. Explain the time dependence for t large. (Which force term i

The measured volumetric flow rate of ethane at 10.0 atm absolute and 35C is 1.00 X 103 Llh. Using an estimated value of the second virial coefficient in the truncated virial equation (Equation 5.3-4), (a) calculate V(Llmol); (b) estimate the compressibility factor, Z; and (c) determine the mass flow

Suppose that a polymer of glucose with alternating \(\alpha(1 \rightarrow 4)\) and \(\beta(1 \rightarrow 4)\) glycosidic linkages has just been discovered. Draw a Haworth projection for a repeating tetramer (two repeating dimers) of such a polysaccharide. Would you expect this polymer to have primari
