Which outcome results when increasing channel roughness impacts laminar flow modeled with Poiseuille's equation?

💡 Explanation

Increased roughness increases the viscous effects, invoking a larger pressure gradient through heightened friction, because Poiseuille's equation assumes constant viscosity; therefore, increased pressure drop is needed rather than cavitation near the walls.
