Challenge Problems
Push your limits with challenges.
Question 1
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.
Question 2
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.
