A fluid power system comprising a fluid pump and an impulse turbine operating in the incompressible domain wherein the pump is characterized by a pressure versus flow curve that is inversely interdependent and by a predetermined pump optimum flow area that is associated with maximum pump output power and the turbine includes an inlet flow path to the turbine rotor the effective area of which is substantially matched to the pump optimum flow area to constrain pump operation to the region of maximum output power.
