Several factors can affect flow rate in nanoscale systems:
Channel dimensions: Smaller channels can restrict flow, requiring higher pressure to achieve the same flow rate as larger channels. Fluid properties: Viscosity and density of the fluid play a significant role in determining the flow rate. Surface interactions: At the nanoscale, surface properties such as wettability and roughness can significantly impact flow rate. External forces: Electric and magnetic fields can be used to manipulate flow rate in certain nanofluidic applications.
