A fluid with a viscosity of 0.75 Pa.s flows between two plates 5 cm apart. If the velocity gradient is 3 s⁻¹, calculate the shear stress and discuss its implications in fluid dynamics.
💡 Hint: Use the shear stress equation we discussed.
Calculate shear stress for a fluid where the viscosity is decreased from 0.7 Pa.s to 0.3 Pa.s while maintaining the same velocity gradient. What does this reveal about fluid behavior?
💡 Hint: Reflect on the relationship between viscosity and shear stress.
