Reynolds Number
The Reynolds Number is a key concept chemical engineers use to understand how fluids (liquids and gases) move through pipes and equipment. Think of it as a measuring tool that helps engineers predict whether a fluid will flow smoothly (like honey) or create turbulence (like water from a garden hose). This understanding is crucial for designing safe and efficient industrial processes, from oil refineries to food production plants. When you see this term in a resume, it shows the candidate has practical experience with fluid flow calculations and process design.
