Question
Download Solution PDFFind the Reynolds number (R) for liquids flowing through cylindrical pipe, wherein V is velocity of the liquid, ρ is density of the liquid, η is coefficient of viscosity of the liquid and D is diameter of the pipe.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 2):(R = V ρ D / η)
Concept:
- Reynold's number: It is a pure number that determines the nature of the flow of liquid through a pipe. I
- t is defined as the ratio of the inertial force per unit area to the viscous force per unit area for a flowing fluid.
- Reynold's number is written as NR.
- V is the velocity of the liquid, ρ is the density of the liquid, η is the coefficient of viscosity of the liquid and D is the diameter of the pipe.
