Hot mix asphalt (HMA) is commonly used in the construction of roadways in the United States at a rateestimated to be 500,000,000 tons/year. A typical upper layer (there may be as many as 5 layers ofdifferent thicknesses and compositions) of a high-volume highway is composed of crushed stone (alsoknown as crushed aggregate) and asphalt binder and is approximately 1.25 inches thick. The stone,which has a specific gravity of about 2.7, is mixed with asphalt binder (SG = 1.03) to form the HMAwith a composition of approximately 95 wt% aggregate and 5% asphalt. What is the volume ft3 of asphalt binder and weight (tons) of HMA required for the top layer of a 15-mile segment of interstatehighway with 5 lanes, each of which has a width of 12 ft?

Diluted skim milk with a protein concentration of 4.3 g/L is to undergoDEF microfiltration. Experiments have been performed using a cellulose-acetate membrane with an average pore diameter of 0.45 µm and AM = 17.3 cm2. For Stage 1 operation at a constant-permeate rate of 15 mL/minute, pressure drop across the cake and membrane increases from 0.3 psi to an upper limit of 20 psi in 400 seconds. The permeate viscosity is 1 cP. If continued in a second stage at constant ∆P at the upper limit until the permeate rate drops to 5 mL/minute, estimate the additional time of operation.Prepare plots of permeate volume in mL and permeate flux in mL/cm2-minute as functions of time.

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.
