Reynolds number for flow of water at room temperature through 2 cm dia pipe at an average velocity of 5 cm/sec is around________________?
Correct answer: D. 1000
- A. 2000
- B. 10
- C. 100
- D. 1000
Explanation
Using Re = ρvD/μ for water, Re ≈ (1000)(0.05)(0.02)/(0.001) = 1000. Thus the nearest option is 1000.
