Question 2 of 10
2. Question
Assume liquid streaming in a cylinder strongly. The speed limit layer creates along with the cylinder. The thickness of this limit layer increments in the stream course until the limit layer arrives at the cylinder place. This area from the cylinder delta direct at which the limit layers converge at the centerline is called?
Correct
Hydrodynamic section locale is defined by the area from the cylinder delta direct at which the limit layers converge at the centerline.
Incorrect
Hydrodynamic section locale is defined by the area from the cylinder delta direct at which the limit layers converge at the centerline.
