does nozzle increases pressure & ke
In a convergent nozzle, there is an increase in velocity and a decrease in pressure, but we know that pressure is inversely proportional to area. Then why is this pressure decreased in convergent nozzle, although there is a decrease in area? The pressure drops in a convergent nozzle because of the Bernoulli Principle. A nozzle is a spout on the end of a hose or pipe used to control the movement of a fluid like water or air. A convergent nozzle is a nozzle that starts big and gets smaller-a decrease in cross-sectional area. As a fluid enters the smaller cross-section, it has to speed up due to the conservation of mass.
