Pv Diagram Of Rankine Cycle

The rankine cycle was named after him and describes the performance of steam turbine systems though the theoretical principle also applies to reciprocating engines such as steam locomotivesin general the rankine cycle is an idealized thermodynamic cycle of a constant pressure heat engine that converts part of heat into mechanical work. Cold liquid at initial temperature is pressurized reversibly to a high pressure by a pump.

A schematic of the components of a rankine cycle is shown in figure 811the cycle is shown on and coordinates in figure 812the processes in the rankine cycle are as follows.

Pv diagram of rankine cycle. Energy added in steam generator q 1 h 3 h 2. Application of the first law of thermodynamics to the control volume pump steam generator turbine and condenser gives. It plays a major role in steam power plants.

Theory of rankine cycle. The rankine cycle is often plotted on a pressure volume diagram pv diagram and on a temperature entropy diagram ts diagram. The working fluid at the inlet repeatedly undergoes change of phase and in successive operations energy is transmitted and output power is produced.

Work done on pump per kg of water w p h 2 h 1. The rankine cycle is the fundamental operating cycle of all power plants where an operating fluid is continuously evaporated and condensed. Ideal rankine cycle a schematic representation of an ideal rankine cycle b t s diagram of an ideal rankine cycle.

When plotted on a pressure volume diagram the isobaric processes follow the isobaric lines for the gas the horizontal lines adiabatic processes move between these horizontal lines and the area bounded by the complete cycle path. This cycle is mainly based on the conversion of input heat energy into output power using turbine. Rankine cycle ts diagram.

In this process the volume changes slightly. Figure 1 shows the idealized rankine cycle. Simple rankine cycle is an ideal vapour cycle.

The selection of operating fluid depends mainly on the available temperature range.
