"Great," Miller grunted. "Call the vendor. They'll send a proposal in... three weeks."
The fluorescent lights of the pilot plant hummed, casting a sterile glare over the stainless-steel tank. Raj stared at the vessel, his forehead beaded with sweat. He was the new process engineer at ChemiCorp, and he had exactly twelve hours to fix a batch that looked more like cottage cheese than the smooth emulsion the client was paying for. agitator design calculation xls
"It’s the agitator," muttered Old Man Miller, the plant supervisor, leaning against a railing. "That off-the-shelf impeller you boys ordered? It’s about as useful as a spoon in a bucket of concrete." "Great," Miller grunted
"We can't just guess a bigger motor," Raj said, tapping his pen against his clipboard. "If we overpower it, we shear the product. If we under-power it, we ruin the batch. We need to calculate the Reynolds number, the power number, and the specific pumping rate." three weeks
Raj nodded grimly. The viscosity of the batch had increased unexpectedly during the reaction phase. The current agitator was creating a vortex but no vertical turnover. The solids were settling at the bottom, essentially baking onto the heat transfer surfaces.
