For Problem 1.6, find the distance the particles travel before reaching 99 percent of terminal speed. Plot the distance traveled as a function of time.
1.6 In a pollution control experiment, minute solid particles (typical mass 1 × 10−13 slug) are dropped in air. The terminal speed of the particles is measured to be 0.2 ft/s. The drag of these particles is given by FD = kV, where V is the instantaneous particle speed. Find the value of the constant k. Find the time required to reach 99 percent of terminal speed.

One of the attempts to contain the spill involved pumping drilling mud into the well to balance the pressure of escaping oil against a column of fluid (the mud) having a density significantly higher than those of seawater and oil.In the following problems, you may assume that seawater has a specific gravity of 1.03 and that a hypothetical subsea wellhead is 7167 ft below the surface of the Gulf. Gauge Pressure Estimate the gauge pressure (psig) in the Gulf at a depth of 7167 ft. ______psigarrow_forwardfluid mechanics- vorticesarrow_forward
- A centrifuge is a device in which a small container of material is rotated at a high speed on a circular path. Such a device is used in medical laboratories, for instance, to cause the more dense red blood cells to settle through the less dense blood serum and collect at the bottom of the container.
