Question

Water flows into a tank which is 200 m long and 150 m wide, through a pipe of cross-section (0.3m x 0.2m) at 20 km/h. In what time will the water level be 12m ?

Answer 1

Answer:
=======

Volume of water collected in the tank in 1 hour.

So,

$(0.3 × 0.2 × 20km × 1000mts) = 1200 m^3$

If after t hours, the water is at height of 12m.

So,

$1200t = 200 × 150 × 12$ 

$1200t = 360000$

$t = \frac{360000}{1200}$

$t = 300 Hours$

Therefore,

Answer: 300 Hours.

Heyy mate ❤✌✌❤

Here's your Answer.....

⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️

Volume of water collected in the tank in 1 hour

⇒ (0.3 × 0.2 × 20km × 1000mts) = 1200 m cubic

If after t hours, the water is at height of 12m,

1200t=200×150×12 

⇒ t = 300 Hours.
