Difference between streamline motion and turbulent motion.
i) It is an orderly type of motion in which the liquid flows in parallel layers while, turbulent motion is disorderly type of motion.
ii) Every particle of the liquid follows the path of it's preceeding particle and travel with the same velocity in magnitude and direction whereas, the motion of particles of the liquids becomes different at different points in turbulent flow.
iii) The velocity of streamline flow is less than critical velocity but, in turbulent motion the liquid moves with a velocity greater than the critical velocity of the liquid.
iv) Streamline flow is laminar whereas, turbulent flow is non-laminar.
Bernoulli's equation.
Explain why:
(b) Atmospheric pressure at a height of about 6 km decreases to nearly half of its value at the sea level, though the height of the atmosphere is more than 100 km.
