✦ Synopsis

Accurate helium properties must be measured to develop refrigeration systems for superconducting motors and generators. Normally when measuring these properties a double iteration is necessary on the equation of state to find density and temperature. In this paper new state equations are developed which eliminate iterative procedures. These equations are subsets of three overlapping sets of reference equations. They are thermodynamically inconsistent to the reference equations by a small degree of error, but have been found useful for many calculations.
