A sample of coarse grained soil 50 mm in diameter and 150 mm long was tested in a constant-head apparatus. The soil sample was prepared at a void ratio of 1.5. The total head was kept constant at 300 mm and the amount of water collected in 4 sec was 50 cm³. The test was made at 22°C. a. Compute the coefficient of permeability in cm/s at the test temperature. b. Compute the coefficient of permeability in cm/s at 20°C. c. Compute the interstitial velocity.

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.
Assume you have 0.5 m3 of soil with a porosity of 40% and an oven-dry weight of 700 kg. Calculate the bulk density. Next, assume that I drive over the soil with heavy equipment, compact the soil, and reduce the porosity from 40% to 20%. Calculate the bulk density after compaction.
Hello, can someone please help me? I have already hand graphed 1 and 2 and found the v max, however I cannot find the Km value. I am confused because the plots on the linear weaver burk plot do not extend past the values that make up the line. So how am I supposed to estimate the value for the y-intercept in order to find the Km value

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.
Suppose that after delivery several drops of water cling to the inner wall of the pipet (because the pipet wall is dirty). Will this technique error increase, decrease, or have no effect on the reported density of the water? Explain.
