202) Two pipe systems can be said to be equivalent, when the following quantities are same

Answer is:

friction loss and flow

203) For pipes, turbulent flow occurs when Reynolds number is

Answer is:

more than 4000

Explanation:

The ratio of the inertia force to the viscous force is called Reynold’s Number. The flow in a pipe is laminar when Reynold’s number is less than 2000 and flow is turbulent when Reynold’s number is more than 2800. But when Reynold’s number is between 2000 and 2800, the flow is neither laminar nor turbulent.
