Answer #1

We have,

Viscosity of air

Density of air

Characteristic length that is Diameter of the object

Velocity of object relative to fluid in which it is in motion

So, the corresponding reynold's number will be given as,

So the value of Reynold's number is,

   ( Expressed in three significant figures )
