nozzle is used where we have high pressure and low velocity or k.e.but we needs low pressure and high velocity.
nozzle are generally of two kinds 1.CONVERGENT 2.DIVERGENT.
the nozzle whose inlet dia is greater and outlet dia is smaller is known as convergent while the nozzle who has low dia at inlet and large dia at outlet is known as divergent type nozzle.
WHEN WE PASS THE FLUID THROUGH A NOZZLE,ITS PRESSURE DECREASES AND VELOCITY INCREASES.
INLET VELOCITY <<<<< OUTLET VELOCITY
INLET PRESSURE >>>>> OUTLET PRESSURE
