Expert writing Tips

Best practice

When describing complex systems, use "a pump in which" to clearly define the operating context or specific mechanism integral to its function.

Common error

Avoid using "where" when "in which" is more appropriate. "Where" generally refers to a physical location, while "in which" describes a condition or context within the pump's operation.
