Pressure in an operating hydraulic system is developed __________.

Correct Answer: Option B — by resistance to the fluid flow through the system

Hydraulic pressure is a function of resistance to flow, not the pump itself, which merely provides volume. When fluid encounters restrictions like valves, actuators, or orifices, the pump's output is converted into pressure. This principle is central to understanding hydraulic system operation and troubleshooting under 46 CFR standards.
