Help Center Help Center. The P-H Diagram 2P block plots a p-h diagram of the pressure with respect to the specific enthalpy of a thermodynamic, two-phase fluid. A p-h diagram indicates the fluid state at key points during a thermodynamic cycle. Each numbered point on the diagram indicates the fluid state after a dynamic process in the refrigeration cycle:. Use a Mux block to combine the pressure signals. Connect the output signal to the P-H Diagram 2P p port. Use a Mux block to combine the converted specific enthalpy signals and connect the output signal to the h port. Before running the simulation, double-click the P-H Diagram 2P block, then click the Select fluid properties button to set the network fluid properties. If you do not select the fluid properties, the block uses the default two-phase network fluid, which is water. You can also replay the animation from the most recent simulation.

The point at which the two curves meet is called the critical point. Entropy is the measure of the amount of disorder in the system.
