P2.6.2.4 pV Diagram of the Hot-Air Engine as a Heat Engine - Recording and Evaluating with CASSY

P2.6.2.4  pV Diagram of the Hot-Air Engine as a Heat Engine - Recording and Evaluating with CASSY In the experiment P2.6.2.4, the pV diagram of the hot air engine as a heat engine is recorded using the computer-assisted measured value recording system CASSY. The pressure sensor measures the pressure p in the cylinder and a rotary motion sensor measures the position s, from which the volume is calculated, as a function of the time t. The measured values are displayed on the screen directly in a pV diagram. In the further evaluation, the mechanical work performed as piston friction per cycleand from this the mechanical powerare calculated and plotted in a graph as a function of the no-load speed.
