Se desea generar potencia eléctrica instalando un generador de turbina hidráulica en un sitio ubicado a 70 m debajo de la superficie libre de un embalse grande de agua que puede suministrar agua a razón de 1 500 kg/s uniformemente. Si la salida de potencia mecánica de la turbina es de 800 kW y la potencia eléctrica es de 750 kW, determine la eficiencia combinada turbina-generador de esta planta. Ignore las pérdidas en tuberías.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
