Glycerin, with a density of 1260 kg/m3 and an absolute viscosity of 1.5 kg/m.s, flows in a tube with an internal diameter of 5,0 cm, but it is not known whether the regime is laminar or turbulent. Knowing that the length of the hydrodynamic inlet of this flow is 0.2 m, determine the velocity of the oil and the flow regime.

Glycerin, with a density of 1260 kg/m3 and an absolute viscosity of 1.5 kg/m.s, flows in a tube with an internal diameter of 5,0 cm, but it is not known whether the regime is laminar or turbulent. Knowing that the length of the hydrodynamic inlet of this flow is 0.2 m, determine the velocity of the oil and the flow regime.
