Multiple Choice

The greater the pressure difference between two points, the ______ the flow rate.

Explanation:
Flow rate is driven by the pressure difference between two points. The bigger the pressure gap, the stronger the driving force pushing the fluid, so more fluid moves per unit time. In simple terms, with a roughly fixed resistance in the path, the flow rate scales with ΔP, so increasing the pressure difference increases the flow. If the pressure difference were smaller, the flow would be slower; options like no change or an inverse relationship don’t fit how driving pressure works.
