Convergent nozzle indicates nozzles will converge with an end closing together at the end
divergent nozzles increase size at the end.
If air flows in this direction: --->
Convergent nozzle > Divergent nozzle <
diffine the converging nozzle and divering nozzle
1) convergent nozzle 2)divergent nozzle
In case of venturi meter, at the diverging section mach number is less than 1. however in diverging section of a nozzle mach number is greater than 1.
A convergent-divergent nozzle is generally used in steam turbines. This is because it drives generators in producing electricity with the use of turbine rotors with curved axes.
Because the fluid is allowed to expand in the nozzle it increases velocity to fill in the voids created by the shape of the nozzle. The convergent point of the nozzle acts like a bottleneck trying to slow the fluid and compress it into the reduced crosssection of the nozzle. As it leaves the minimum crosssection it expands into the divergent spaces of the nozzle increasing in velocity as it expands. ++_+ No: it gains velocity through the convergence but in the diverging section, trades velocity for pressure.
One disadvantage in the convergent-divergent nozzle as a shock wave can take place in the nozzle A nozzle is a device that converts pressure energy to kinetic energy (increasing fluid velocity on the account of static pressure) For a convergent nozzle there is no disadvantages as it can raise the fluid velocity only for the sonic speed the convergent-divergent type raises the velocity to over than sonic speed making supersonic flow, this could make a shock wave in the nozzle that turns the supersonic flow to subsonic flow
coz area is less thats y pressure is more
A NOZZLE IS A DUCT WHICH CONVERT HEAT ENERGY INTO KINETIC ENERGY.IT INCREASES VELOCITY OF FLUID PASSING THROUGH IT ,AT THE EXPENCE OF PRESSURE. STEAM EXPANDS IN NOZZLE FOLLOW RANKINE CYCLE.FLOW THROUGH NOZZLE IS ISENTROPIC. mritunjay04@gmail.com
The answer would be convergent
divergent, transform and convergent
convergent
convergent boundaries collide but divergent boundaries move away from each other.
Convergent.
