Reynolds number is:

  1. a  dimensionless quantity
  2. inversely proportional to viscosity of liquid
  3. directly proportional to velocity of liquid
  4. used for quantifying the laminar or turbulent flow of liquid

Which of the above statements is/are correct?

Answer: [D] 1, 2, 3 & 4

Laminar and Turbulent flow of a liquid is quantified by Reynolds number (Nr)
Nr < 2000 – laminar flow and Nr > 4000 – Turbulent flow
