According to Bernoulli's Principle, the pressure of a fluid decreases with increase in velocity. However I am not able to understand. Can you talk me the logic behind it and describe what is happening molecular level.

Answer:
The pressure in a fluid is due to the molecules hitting the boundary of the tube.
When the fluid has less velocity, the molecules have more time to collide with the boundaries. More time means more force is being exerted. So, the pressure is also more as pressure is Force/area.
Thus, a fluid with high velocity will have decreased pressure.
This can also be seen from the Benoulli's principle
