(10 pts) For quiescent (still water) conditions determine the settling velocity of spheres of four particle...
Determine the settling velocity (m/s) of a sand particle with a density of 2.6 g/cm3 and 1 mm diameter. νw = 1.307x10-6 m2/s and ρw = 998 kg/m3.

mework 7 blem 11.79-Enhanced-with Hints and Feedback Determine the velocity of the particle at which Stokes' law becomes invalid, at about Re Express your answer to three significant figures and include the appropriate units Review A 2.3-mm-diameter sand particle having a density of 2.40 Mg/m3 is released from rest at the surface of oi that is contained in the tube. As the particle fails downward, "creeping flow' will be established around it. The oil has a density of...
Problem 2 - MSH Ch5 Energy Balance and Ch 7 Packed Bed (20 pts). Design a porous straw for camping that can remove contaminant from water, so the water is safe to drink. You would want the straw to feel normal in a mouth. Normal straws have 0.60-cm inner diameters and are usually about 19.5 cm long. The suction strength of a normal adult is about 4000 Pa. Assume the contaminated water (only mildly "dirty" or the straw would clog)...
