Working fluid thermodynamic properties (WFTP) are the essential parameters for the design of turbo machinery which is widely used in the fields of petroleum, chemical industry and energy.Meanwhile.they also can be employed to evaluate and predict the thermal performance of turbo machinery [1, 2].The formula approach and table looking-up method whose theory could meet the needs of engineering are always used to calculate WFTP.
