Which of the following is an appropriate SI unit for measuring flow rate?

• A. m^3/s
• B. kg/m^3
• C. Pa
• D. mol/L

Answer: (A)

Verified step by step guidance

1. Understand that flow rate is a measure of the volume of fluid passing through a surface per unit time.
2. Recall that the SI unit for volume is cubic meters (\(m^3\)) and the SI unit for time is seconds (\(s\)).
3. Combine these units to express flow rate as volume per time, which is \(m^3/s\).
4. Analyze the other options: \(kg/m^3\) is a unit of density, \(Pa\) (Pascal) is a unit of pressure, and \(mol/L\) is a unit of concentration.
5. Conclude that the appropriate SI unit for flow rate among the options given is \(m^3/s\).
