Ok got it, thanks.

This graph was taken from the NIST webbook and shows a vapour pressure of 0.6 bar at 180K, ok so maybe the liquid does not vapourise in the tank but the liquid must come out because you have a pressure difference of 49 bar across the orifice.

The vapour pressure for nitrous oxide at 180K is around 0.6152 bar. I don't mind the assumption that the system is adiabatic but I think the system should not be isothermal as the tank will cool as the vapoursied fluid leaves the tank. As for gravity I am not sure. I only really care about...

There is a relief valve at the top of the tank, so at the start the tank can be considered to be comprised of 100% liquid nitrous oxide pressurised at 50 bar with a temperature of 180K. A valve at the bottom of the tank with a diameter (Do) is opened. The exit plane of the orifice can be...

The N20 would be in the gaseous phase and will want to expand at the exit plane of the orifice.

Well Actually I have already designed a similar tank and calculated the longitudinal stress and hoop stress that the nitrous oxide might impart on the vessel in question. I also carried out FEA on the tank to back up hand any calculations. All stresses are well below the youngs modulus of the...

Homework Statement I want to design a closed tank with an orifice hole (that can be opened and closed remotely) at the bottom of the tank and model how the mass flow rate of liquid nitrous oxide changes with respect to time, as the liquid nitrous oxide leaves the tank due to a pressure...
