Paper format. 16-CHEM-A2, Unit Operations and Separation Processes — December 2019, 3-hour open-book exam. Six 25-point problems: Part A (Unit Operations) — A1 pump-power from a full mechanical-energy balance, A2 terminal velocity & matched fluidized-bed densities, A3 constant-pressure plate-and-frame filtration; Part B (Separation Processes) — B1 countercurrent rotary-drier air rate, B2 Swenson–Walker crystallizer sizing, B3 double-effect forward-feed evaporator capacity. The rubric asks for two problems per part; all six are worked in full below.
