Measurement of Sodium Vapour Pressure Using Sodium as Manometer Fluid

Abstract

The pressure of saturated sodium vapour in the range 1114–47 500N/m2 is measured using a sodium manometer developed for this purpose. Commercially obtainable reactor grade sodium is used and is found to follow the equation log P= 9.36037-(5048–74/r), where P is in N/m2 and T in Kelvin.
