Question

Find the time taken to discharge industrial affluents
from a cubical tank of side 2,000 mm if the flow rate
of the affluents is 100 ml per second.​

Answer 1

Answer:

Side of cubical tank is 2000mm = 2metre

so volume of cubical tank = (side)³

= (2)³= 8m³

and rate of flow of affluents = 100mL per second.

We know that ,

$1l = {10}^{ - 3} \: {m}^{3}$

So,

$1ml = {10}^{ - 6} \: {m}^{ 3}$

So, Rate of flow = 100 mL/sec

$= 100 \times {10}^{ - 6} {m}^{3} \: per \: sec$

$= {10}^{ - 4} {m}^{3} \: per \: second$

$time \: taken = \frac{volume}{rate \: of \: flow}$

$= > \frac{8 {m}^{3} }{ {10}^{ - 4} {m}^{3} per \: second}$

$= > 8 \times {10}^{4} seconds$
