Challenge Problems
Push your limits with advanced challenges
A raindrop falls through air and reaches terminal velocity of 9 m/s. If the mass of the drop is 0.002 kg, calculate the drag force acting on it.
💡 Hint: Use the weight formula.
A viscous fluid flows between two parallel plates with a 5 mm gap. If one plate moves at 0.1 m/s and shear stress is measured at 200 Pa, calculate the dynamic viscosity.
💡 Hint: Consider the height difference to derive du/dy.
