Mi querido Bernoulli: Nota : aquí, k q es solo de la bomba. h B es la energía por unidad de peso dada por el eje de la bomba. Los fabricantes de bombas dan H B : U D z U + p U γ + v U 2 2 g + h B ( q )= z D + p D γ + v D 2 2 g + k q q 2 z U + p U γ + v U 2 2 g + H B ( q )= z D + p D γ + v D 2 2 g donde: H B ( q )= h B ( q )− k q q 2 pero también dan el rendimiento: η( q )= H B ( q ) h B ( q ) Estaciones de bombeo: bombas

    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.
