indicator diagram

In the technology of the steam engine, the indicator diagram was a device developed by James Watt and his employee John Southern to improve the efficiency of engines.The diagram is simply a chart of the pressure of steam in a cylinder against the steam's volume. In 1796, Southern developed the simple, but critical, technique to generate the diagram by fixing a board so as to move with the piston, thereby tracing the "volume" axis, while a pencil, attached to a pressure gauge, moved at right angles to the piston, tracing "pressure".

A plot of pressure vs. volume. Lines or curves on the indicator diagram represent processes. The areas under curves on the indicator diagram are equal to the work released by the process.
