Answer:
Positive logic is defined as a high voltage level representing a logic 1 and a low voltage level representing a logic 0. Negative logic is the reverse, i.e., a low voltage level represents a logic 1 and a high voltage level represents a logic 0.

Thanks
Answer:
No, I disagree
Explanation:
The average velocity in a circular pipe in fully developed laminar flow cannot be defined by simply measuring the velocity at R/2 (midway between the wall surface and the centerline). Vmax/2 is the mean velocity, but the velocity at midway between the wall surface and the centerline is
Where R represent the circular pipe radius and r is a local radial distance measured from center of the pipe to any desired point
