Challenge Problems
Push your limits with challenges.
Question 1
A liquid with a viscosity of 0.8 Pa·s flows through a pipe of diameter 30 mm at an average velocity of 1.5 m/s. Calculate the Reynolds number and determine if the flow is laminar or turbulent.
💡 Hint: What is the density assumption based on specific gravity?
Question 2
Identify the pressure difference required for maintaining a constant flow rate of 0.005 m³/s in a horizontally placed pipe of 40 mm diameter having a length of 50 m and a viscosity of 0.1 Pa·s.
💡 Hint: Focus on understanding the effect of radius and viscosity on flow.
