The coefficient of friction of a laminar flow is

  1. Re/16
  2. Re/64
  3. 16/Re
  4. 64/Re

Answer: A- 16/Re

The coefficient of friction of a laminar flow is 16/Re

Solution:

The value of the coefficient of friction within a smooth pipe depends on the Reynolds number and flow type. For laminar flow, the coefficient of friction depends only on the Reynolds number, and the value is 16/Re.

Where,

  • Friction factor = Re/64
  •  Re is Reynolds number
