Estimate the reynolds number for a human swimming in water. approximate the human as a sphere of radius 0.50.5m, swimming at a speed of about 11m/s. the density of water is approximately 1000\text{kg/m}^31000kg/m 3 and its viscosity is 0.001\text{n/m}^2\cdot\text{s}0.001 n/m 2 ⋅s.

Re= 5*10^5

Step-by-step explanation:

The numbers are not totally clear as they repeat each other. Under this consideration I will assume the closest values according to the advertised.

r=0.5m

V=1m/s (or) V=11m/s

We know that Reynolds number is given by,

Or for the another velocity
