## Pressure volume diagram for steam

Why work from expansion is the area under the curve of a PV-diagram. Why heat is not a state function and internal energy is a state function. Rankine Cycle - pV, Ts diagram. The Rankine cycle is often plotted on a pressure volume diagram (pV diagram) and on a temperature-entropy diagram (Ts  26 Sep 2011 Steam tables for superheated steam are organized by pressure and temperature The curve on the P-V and T-V diagrams in the solution is the

Working on steam engine, indicator diagram is plotted by the modified Rankin cycle.Before developing the indicator diagram of steam engine, we should consider the following points.It will help to understand the indicator diagram. 1. The steam enters in boiler pressure and released at condenser pressure. 2. The opening and closing steam ports are instantaneous. 3. Steam is hyperbolic at the time of expansion or compression which is pv=c. 4. Steam pressure remains constant at the time of Specific volume of superheated steam: In this table at every absolute pressure the specific volume of supercritical steam is given. Enthalpy of supercritical steam: In this table at every absolute pressure the enthalpy of supercritical steam is given. The enthalpy in saturated steam (x = 1, the bold red line in the diagram) with pressure 10 bar can be estimated to aprox. 2770 kJ/kg. The value can be verified by using the steam table. This spreadsheet provides a template for analysis of the Rankine (steam) Cycle. The user must fill in the data in the top grid (from other software or table lookup). From that data, the cells in the second grid are updated, and Pressure-volume and Temperature-entropy diagrams are generated. The bold line, spanning from left to right, in the lower half of Mollier diagram is the saturation line. The saturation line, labeled as x = 1, represents the set of points on Mollier diagram where the steam is 100% vapor. All points above the saturation line are in the superheated steam realm.

## Steam at atmospheric pressure is of a limited practical use because it cannot be conveyed by its own pressure along a steam pipe to the points of use. In a steam distribution system the pressure is always more than 0 bar gauge.
