- El actuador rotatorio de un sistema hidráulico recibe 37 de aceite, presurizado
a 2.0 manométrico. El actuador aplica un par de 920 sobre la carga
externa, mientras recorre su carrera angular de 48° 1.2 ¿Con qué eficiencia se
convierte la energía hidráulica en trabajo mecánico?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
