Hello
here is a schematic of the problem: http://imgur.com/CgcybVT
A stream of helium gas will be used to carry aerosolized particles.
I am assuming conservation of mass (and mass flow)
The mission is to find the exit stream velocity of the gas. For the time being, i am assuming the weight of particle is negligible and doesn't reduce helium velocity.
I am using Bernoulli's equation... would it be correct to only focus on the inlet and exit ?
I feel the changes in area matter because as area increases, velocity decreases to maintain constant mass flow.
Advice?
Thanks!
EDIT: I forgot to mention the system is under vacuum, and he outlet pressure of 0.065 psi is that of the vacuum chamber
here is a better diagram: http://imgur.com/64b7WLT
