Can we apply Euler's Equation and continuity equation to compressed air flow from tank or orifice.
Sure, as long as you have an appropriate equation of state, such as the ideal gas law. Also, Euler's equations assume that the flow is dissipation free, and the system you describe is almost certainly neither adiabatic nor entirely inviscid, so there will be some error inherent in those assumptions.
Thank you sir for your fast reply,
As i have engine and as power source is compressed air and process assumed is adiabatic then how i can apply here in my system.
