Challenge Problems
Push your limits with advanced challenges
Calculate the Reynolds number for oil with a density of 850 kg/m^3 and viscosity of 0.1 Pa.s flowing through a pipe of diameter 0.05 m at a velocity of 2 m/s. Determine whether the flow is laminar, transitional, or turbulent.
💡 Hint: Use the Reynolds number formula; remember the definitions of flow types.
In a scenario where you double the flow rate of water in a pipe, how does that affect the Reynolds number and flow type? Explain your reasoning.
💡 Hint: Analyze how Reynolds number is affected by velocity and initially known conditions.
