Flow can be expressed as?

• A. Psi
• B. Gpm
• C. Ppm
• D. Mph

Answer: (B)

Flow is the rate at which liquid moves past a point, expressed as volume per unit time. In wastewater work, gallons per minute is a common way to express flow because it tells you exactly how much wastewater is passing each minute. Psi, pounds per square inch, is a measure of pressure, not how much liquid is moving. Ppm, parts per million, describes concentration, not flow. Miles per hour measures speed, not the amount of liquid flowing. So the best expression of flow among these options is gallons per minute, since it directly represents volume moving per unit time.
