The velocity of the nozzle in a cylinder can be calculated by dividing the displacement by the amount of time. For example, if 1 cubic foot of gas is released over 1 minute, it would have a velocity of 1 foot per minute.
V= q/a
The velocity of gaseous or other particles in the exhaust stream of the nozzle of a reaction engine, relative to the nozzle.
A nozzle is a device which increases the velocity of fluid by decreasing the Pressure but contrary to it Diffuser is a device that increases the Pressure of fluid at the expense of its velocity
By Bernoulli's principle velocity head x pressure head is always constant So as velocity increases at the nozzle the pressure falls down automatically.
You convert the flow into m3/s and then divide that by the total area of the cylinder (m2) to give you the passing velocity in m/s. The key is finding the total area of the screen, which will depend on slot size, slot spacing, and cylinder type.
V= q/a
The velocity of gaseous or other particles in the exhaust stream of the nozzle of a reaction engine, relative to the nozzle.
How to calculate the ratio of the inlet-to-exit area of the nozzle
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.
To increase the exhaust velocity. +++ Pressure, not velocity. A gas flowing through a divergent nozzle gains pressure at the cost of speed.

Hammer piston velocity is: Velocity of an pneumatic cylinder can be calculated as s = 28.8 q / A (1) where s = velocity (inches/sec) q = volume flow (cubic feet/min)A = piston area (square inches) Do you know how to calculate the impact PSI? - This is where I get lost.
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
Nozzles are designed to increase the steam velocity.
It sends hot gases from the combustion chamber to the 1st stage turbine blades at the correct angle and speed
