WebThis quantity also can be evaluated at state 1 from the generalized enthalpy departure chart, Fig. A-4, using the reduced temperature T R 1 and reduced pressure p R 1 corresponding to the temperature T 1 and pressure p 1 at the initial state, respectively. WebI'm pretty sure it's just a chart that uses the law of corresponding states to help someone evaluate the change in state of enthalpy in a generalized way using departure functions. You use it to assist in finding a change in the enthalpy, and the "departure" aspect of it refers to how far away the gas' behavior is to an ideal gas.
