Question

A common household faucet has a flow rate of around $5\text{L/min}$. What is this flow rate in $\text{m}{}^3\text{/hr}$?

• A. 0.1
• B. 0.5
• C. 0.3
• D. 0.6

Answer 1

The correct option is C 0.3

First we need to know the two conversion factors for each set of units.

Volume: $1000\text{L}=1{\text{m}}^3$

Time: $60\text{min}=1\text{hr}$
So $5\text{L/min}=\frac{5\times \frac{1}{1000}}{\frac{1}{60}}=0.3\frac{{\text{m}}^3}{\text{hr}}$
