A flow of liquid is streamline if the Reynold number is

Options

  1. Aless than ( 1000 )
  2. Bgreater than ( 1000 )
  3. Cbetween ( 2000 ) to ( 3000 )
  4. Dbetween ( 4000 ) to ( 5000 )

Correct answer

A. less than ( 1000 )

Step-by-step solution

The Reynolds number is the ratio of inertial forces to viscous forces. It predicts weather the flow will laminar or turbulent. A flow of liquid is streamline if the Reynolds number should be less than 2000. Therefore, from the given options, only option (1) satisfies the condition. Thus, a flow of liquid is streamline if the Reynolds number is less than ( 1000 ).
