A mathematical model for gas velocity distributions and definition of flow types is applied to a helium plasma operated at 27 kW and a gas flow rate of 7.2 g/minute under pressures of 760 mm and 300 mm Hg. The calculated velocity data are used to predict values of thermal conductivity and viscosity for helium in the plasma. A good approximation to theoretical values is obtained, lending validity to the model of velocity distributions.
