When a sphere of radius r1 = 1.2 mm moves in glycerin, the laminar flow is observed if the velocity of the sphere does not exceed v1 = 23 cm/s. At what minimum velocity v2 of a sphere of radius r2 = 5.5 cm will the flow in water become turbulent? The viscosities of glycerin and water are equal to n1 = 13.9 P and n2 = = 0.011 P respectively. |
