A pump produces __________.

• A. Pressure
• B. Torque
• C. Flow
• D. Temperature

Answer: (C)

Pumps are designed to move fluid, so the quantity you describe as what a pump produces is the flow—the rate at which fluid is moved through the system (for example, liters per minute or cubic meters per hour). The pump also creates a pressure rise to push the fluid against system resistance, but that pressure is a consequence of driving the flow and the system," not the primary output itself. Temperature isn’t the intended output of a pump; any change in temperature would come from inefficiencies or other heat sources. Torque relates to the drive motor’s force to turn the pump, not the fluid’s movement. So the best description of what the pump produces is the flow.
