If it takes 5.0 hrs to drain a container of 540.0m\(^3\) of water, what is the flow rate of water from the container in kgs\(^{-1}\)? [Density of water = 1000kgm\(^{-3}\)]
A
32.5kg-1 s
B
31.5kg-1
C
30.8kg-1 s
D
30.0kg-1 s
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Flow rate = \(\frac{mass}{time}\)
= \(\frac{1000 \times 540}{5 \times 3600}\)
= 30.0kgs\(^{-1}\)
