Calculation of Z-factor using recently published papers. Given the pseudo-reduced pressure, pseudo-reduced temperature, and Z-factor in the attached Excel sheet. 1- Evaluate the following published papers, i.e. compare the estimated versus the experimentally measured Z- factor using some the published methods such as: -Beggs-Brill 1973 -Heideryan et al 2010 -Aziz et al 2010 -Sanjari 2012 -Bahadori-Vuthaluru 2010 -Al-anzi-Al-quraishi 2010 -Kareem et al 2016 -Ganganis et al 2019 -Wei et al 2023 2- Modify the constants in the above methods using the experimental data and compare the estimated versus the experimentally measured values. 3- Tabulate the statistical errors (Er average relative error, EA average absolute error, STD standard deviation, and R coefficient of regression) for each method in (1) and (2).
