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

If pressure is less than atm pressure how fluid will come out from throat?

Please explain the process.

PV=CONSTANT.

AREA DECREASE THAN VELOCITY INCREASE.
Therefore;

PV=CONSTANT.
PRESSURE IS INVERSELY PROPORTIONAL TK VELOCITY.
Therefore, PRESSURE DECREASE.

Area and pressure indirectly proportional to velocity.

How? Can any one explain about it?

At throat, velocity increases but pressure decreases.
