Which risk increases when pumping viscous oil through an unheated pipeline?

💡 Explanation

Increased pumping viscosity directly causes increased shear stress within the pipe via viscous action because a greater force opposes fluid motion; therefore, pressure drop increases to overcome this viscous drag, rather than leading to changes in flow stability.
