Chromite ore processing residue-contaminated soils (COPR-soil), containing large amounts of highly mobile and carcinogenic hexavalent chromium (Cr(VI)) [17], [24], pose a serious threat to ecological safety and public health.Chemical reduction is the most widely used method because of its economic feasibility and …
We describe Chromium, a system for manipulating streams of graphics API commands on clusters of workstations. Chromium's stream filters can be arranged to create sort-first and sort-last parallel graphics architectures that, in many cases, support the same applications while using only commodity graphics accelerators. In addition, these stream ...

Question: 3. (10 points) You are designing a chromium electroplating process on a cylindrical rod. Air at a temperature of 18°C (P = 1 atm) and a velocity of 18.2 m/s flows in cross-flow over the rod just after removal from the electroplating process. The rod has a diameter of 0.15 m, is 1.45 m long and is at a temperature of 62 °C.
