Challenge Problems
Push your limits with advanced challenges
You have a liquid with a viscosity of 1.5 poise and a specific gravity of 0.9 flowing through a pipe of diameter 100mm over 20m. Calculate the pressure difference when 100 kg is collected in 25 seconds.
💡 Hint: Focus on converting poise to Pascal seconds first.
Analyze how an increase in pipe diameter would affect the pressure drop experienced in laminar flow and reason your answer based on the equations.
💡 Hint: Think about the relationship established in Poiseuille's Law when diameter changes.
