Document Summary

4:27 pm quality: mass of vapour divided by total mass specific volume: volume divided by mass; 1 over density to find the specific volume, v, given quality in a compressed liquid linear interpolation. Work is a path function, ie. it depends on the path between states. Quasi-static this only happens for ideal gases, where. Work against a spring varies linearly as a function of volume (assuming it"s a linear spring, ie. ) Internal energy specific internal energy is a property in our tables (like v) in a compressed liquid. During a constant pressure process, use this equation to calculate enthalpy specific heat, c, is defined as the amount of heat required. per unit mass, to raise the temperature 1c or 1k. During a constant volume process, use this equation to calculate internal energy. Constant specific heat: use this equation to calculate enthalpy.
