At throat, velocity increases but pressure decreases.

How? Can any one explain about it?

Area and pressure indirectly proportional to velocity.

PV=CONSTANT.
AREA DECREASE THAN VELOCITY INCREASE.
Therefore;
PV=CONSTANT.
PRESSURE IS INVERSELY PROPORTIONAL TK VELOCITY.
Therefore, PRESSURE DECREASE.

If pressure is less than atm pressure how fluid will come out from throat?
Please explain the process.
Please explain the process.

Pressure =Force/Area
If we put Area =Q/v in the above equation we get
P= force * velocity/discharge (Q).
So, Pressure is directly proportional to velocity in other words Area decreases both Pressures, as well as velocity, will increases
