Question 1
A channel with dense fluid flows at 1.5 m/s, with hydraulic radius of 0.2m, and viscosity 0.0007 Pa·s. What’s the flow regime?
💡 Hint: Remember to use the Reynolds number formula based on provided parameters.
Question 2
In a lab, water has a low viscosity and flows slowly through a pipe. If the velocity is 0.03 m/s, what can you conclude about the Reynolds number?
💡 Hint: Use the small flow conditions to evaluate likely flow characteristics.
