Thermo Formula

This document contains equations describing various thermodynamic processes including adiabatic processes, nozzles, turbines, compressors, and pumps. It defines key terms like the ratio of specific heats (γ), various efficiencies (η), and equations relating temperature (T), pressure (P), volume (V), enthalpy (H), and entropy (S) during these processes. The equations show relationships between initial and final states for processes involving changes in temperature, pressure, volume, and the transfer and conversion of work.
