A large manufacturer of air compressors is developing an air-cooled piston model and a water-cooled piston model, each having a diameter of 5 inches. The prototype was harnessed to a pressure gauge and the following readings were taken during the compression stroke. For each model, find the polytropic index, n, of this process and calculate the non-flow work done. Which of the prototype designs will be more efficient?
