Using the first law of thermodynamics of a medium of variable mass, the equation of conservation of mass, and the differential relations of thermodynamics, a unified system of equations is developed by means of which analyses of the working processes of positive-displacement compressors and pumps that take into account thermal, deformational, and mass-exchange interactions may be conducted.
