PREDICTION OF THERMAL PRESSURE COEFFICIENT OF RUBIDIUM FLUID USING SOME DEVELOPED EQUATIONS OF STATE

For thermodynamic performance to be optimized particular attention must be paid to the fluid s thermal pressure coefficients and thermodynamic properties. The thermal pressure coefficient (TPC) of liquid Rubidium was measured using pvT data at pressures 10 to 100MPa in the temperature range from 500 to 1600K. The Goharshadi- Morsali- Abbaspour equation of state, the so-called GMA EOS and Ghatee- Bahadori equation of state, the so-called GB EOS are used to calculate of thermal pressure coefficients of Rubidium fluid.
