In case of fluid flowing on horizontal surface the flow of fluid becomes unsteady when Reynolds number (Rn) is

Options

  1. Aless than 499
  2. Bbetween 500 - 999
  3. Cbetween 1000 - 1999
  4. Dgreater than 2000

Correct answer

C. between 1000 - 1999

Step-by-step solution

According to the standard classification of fluid flow based on Reynolds number ( R_e ): For R_e For 1000 For R_e > 2000 , the flow is turbulent. Therefore, the flow becomes unsteady when the Reynolds number is between 1000 and 1999 .
