Question

Estimate the Reynolds number for a 1 meter diameter sphere in a water flow of 1m/s at 20°C and atmospheric pressure.

Answer 1

Answer:

Reynolds number= Diameter×velocity×density/viscosity

so Nre= 1*1*1000/0.00089 =1123595

so it is a turbulent flow.

Explanation:

if the Reynold number is greater than 4100 it is turbulent flow
