If it takes 5.0 hrs to drain a container of 540.0cm3 of water, what is the flow rate of water from the container in kg-1? [Density of water = 1000kgm-3]
- 32.5kg-1 s
- 31.5kg-1
- 30.8kg-1 s
-
30.0kg-1 s
The correct answer is: D
Explanation
Flow = rate = \(\frac{mass}{time}\)= \(\frac{1000 \times 540}{5 \times 3600}\)
= 30.0kg-1 s
