Compresores Minimización del trabajo de compresión: Si analizamos el trabajo requerido para efectuar la compresión comparando el consumo de 3 diferentes procesos: a)Isotérmico (P v = constante) b)Politrópico (P v n = constante) c)Isoentrópico (P v k = constante) Y graficamos cada uno de ellos en el diagrama P- v , observa- remos que el mínimo trabajo requerido es el isotérmico para el mismo rango de presiones

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
