A cylindrical container is filled with a Bingham plastic fluid. Calculate the force required to initiate flow if the yield stress is given as 5 Pa and the cross-sectional area of the container is 0.1 m².
💡 Hint: Start by using the yield stress definition.
If the viscosity of a liquid decreases by 10% when the temperature is increased from 20°C to 40°C, calculate the new viscosity if the original viscosity was 0.01 Pa.s.
💡 Hint: Calculate 10% of the initial viscosity first.
