Q1:

The ratio of inertia force of a flowing fluid and the viscous force of the liquid is called :

A Renold's number

B Froude's number

C Euler's number

D Weber's number.

ANS:A - Renold's number

The ratio of inertia force of a flowing fluid to the viscous force of the liquid is called the Reynolds number, named after Osborne Reynolds. Therefore, the correct answer is: Renold's number. (Please note that there seems to be a typo in the options provided; it should be "Reynolds" instead of "Renold's".)
