1. The problem statement, all variables and given/known data I have the data for a p-v diagram from experiment of a fluid (the fluid is unknown). The data is attached below as the crosses. It also has the approximated ideal cycle for that data. Does anyone know how to find the work done for this real experimental data? Maybe a MATLAB command or some other software? Also, would v2/v1 be the compression ratio for this cycle? 3. The attempt at a solution I tried using the trapz function in MATLAB however unsure whether it is correct or not.
