Pressure and Discharge are inversely proportional.

Because flow always goes from higher pressure to lower pressure side, and when difference of pressure increases ultimately discharge increase.

Since if pressure decreases then velocity increases so we know that Q=Av. So velocity increases then discharge also increases.

Some losses in discharge portion.

Due to the low cross section area of the nozzle the molecules will try to escape faster so the force of the molecules per area decreases and the speed increases therefore quantity of molecules passing per second increases.

But the discharge is always same.

Because the discharge from the nozzle is ((2n/n-1)*pv*n/n+1*) so exit pressure and volume not affected on the discharge/ here PV is inlet pressure and volume.

Pressure drop at exit increases net pressure, thus discharge increased.

I think total discharge is same in all portion. Rate of discharged increase.

The discharge is always constant.
