Hey,
I'm working on a project to build a drone which is powered through air jets. The drone needs a valve control system which can control the flow rate (hence the thrust) going to each nozzle in order to adjust it's altitude and stabilty.
I need to set up a circuit which can electronically...
Hey,
I have an air tank that is at a set pressure, say 3000psi, and I have attached a regulator to the end that regulates the pressure down to 800psi. As the valve on the tank is opened the pressure and the mass in the container will decrease. If there was no regulator the mass flow rate would...
Ohhhh I was being stupid about the volume, yes the tank is rigid. In this case I have assumed it is adiabatic. Thanks for your help I will give this a go.
So I have the equation M=C*Pt that I have derived from the choked flow condition. I assume I want to substitute Pt=MRTt/V into this equation to remove the pressure function. However isn't the volume, V, a function of time as well leading back to the same problem with more than one independent...
I'm not sure I understand the differential equation you've set up there, is C some constant and 'm' mass or mass flow rate?
Previously the only differential equation I could think of setting up was -dM/dt = m where 'M' is mass flow and 'm' mass - however I don't see how this helps as it only...
Thanks for the reply.
Im a 5th Year Mechanical Engineering Masters student and have knowledge of C-D nozzles and differential equations. I've set up a similar problem to work out the thrust from a convergent-divergent nozzle for steady flow but confused by how to establish the un-steady flow...
Hey,
So I have a system where there is an air tank (0.2Litres @ 3000psi, 293K) and I have a convergent-divergent nozzle attached directly to it. What I want to know is an expression for how the mass flow rate varies with time as the mass in the tank decreases causing the pressure to decrease...
