You have a fluid flowing over a surface with an observed dynamic viscosity of 1.5 Pa.s and a flow velocity of 3 m/s. If the fluid has a density of 950 kg/m³, calculate the shear stress present.
💡 Hint: Think about how shear stress is derived from viscosity and flow velocity.
A thin layer of oil overlays water. The oil has a viscosity of 8.0 poise at 25°C. If the water is moving beneath it at 1 m/s, calculate the kinematic viscosity of the oil in m²/s.
💡 Hint: Always convert units to standard SI before calculations.
