An iterative method outlined by Green & Southwell (1944), but not applied in their paper for the reason that it makes no use of 'relaxation methods', is here applied to determine the supersonic regime ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

Marked departures from inviscid flow were found when swirling water was discharged downwards under pressure through a Perspex conical nozzle. A boundary layer of forced vortex motion formed on the ...
