Flow rate is defined as which of the following?

Flow rate is defined as which of the following?

• A. The volume moved per unit time
• B. The energy per unit weight of the fluid
• C. The pressure at the pump discharge
• D. The density of the fluid

Answer: (A)

Flow rate measures how much fluid passes a point in a given time. It is defined as the volume moved per unit time, so common units are cubic meters per second or liters per minute. This focuses on the throughput of the system, not on how much energy the fluid carries, the pressure at a point, or the fluid’s density. Energy per unit weight relates to specific energy or head, pressure is the force per area, and density is mass per volume.
